Immigration Policy Is Coming for the 10-Year Game

Previously confined to PC turn-based play, mobile free-to-play transformed 4x into sprawling persistent world MMOs. The combination was and continues to be electric; what other genre can admit to $1M LTVs? Each X,  EXplore, EXpand, EXploit, and EXterminate invites an unparalleled level of feature width and depth. 1 Its LTVs are not driven only by spend depth but also by copious amounts of long-term retention. Like long, long-run retention.

The “10-year game” has gone from a CEO fairy tale to reality. A couple of weeks ago, Clash of Clans (CoC) celebrated its 10th anniversary by grossing over $480 million in the last year alone. But longer lifecycles present new and unexplored challenges. 4x faces a genre-level conundrum: given vertical progression and persistent worlds, what is the most effective way to manage server populations?

The Best Currency Animations of All-Time

Past core loop, three Cs, and KPI breakdowns lie currency animation breakdowns. It’s an animation that may well play hundreds of thousands of times during a player’s lifecycle; benefits compound. And yes, I really think the animation is just satisfying.

Economy design maintains a UX component. It’s vital for the designer to draw the cause <> effect loop between action and reward for the player. Currency animations, played when players claim or complete a task for a reward, stitch the acts into an experience. Wallet amounts don’t magically increase; the currency flows from the claim button to the wallet’s UI location.

The animations amount to a classically conditioned injection of dopamine, not so dissimilar to the original story of classical conditioning-centering on audio-visual reward cues. In that story, Russian scientist Ivan Pavlov presented a stimulus (not a bell!) before feeding a group of dogs. He would collect and measure saliva volume samples after the trigger but before giving the food. Eventually,

[...] Pavlov noted that the dogs would often begin salivating in the absence of food and smell. He quickly realized that this salivary response was not due to an automatic, physiological process.

Based on his observations, Pavlov suggested that the salivation was a learned response. Pavlov's dog subjects were responding to the sight of the research assistants' white lab coats, which the animals had come to associate with the presentation of food. Unlike the salivary response to the presentation of food, which is an unconditioned reflex, salivating to the expectation of food is a conditioned reflex. [1]

Acquisition of a currency is a step removed from acquiring the items the currency can purchase—the time between acquisition and disposal of currency forms anticipation.

Principles of Great Currency Animation

Great currency animations:

  1. Show the currency directly entering the wallet UI location
  2. Ensure the currency reward is hard to ignore
  3. Make the player feel rich while not cheapening the currency signal (i.e., animate more currency than rewarded)
  4. Match animations to powerful audio cues

Mobile Legends Adventure, above, doesn’t showcase a wallet drop-down and violates 3. (notice the number of purple diamonds, it’s less than 200—the actual reward). The audio leaves much to be desired as it only sounds like a single gem has been earned (4. fails).

Game Dev Tychon

The sheer volume of icons is impressive, but the art communicates low-value “points” instead of currency. The currency flow from the computers to the UI location demonstrates the type of assets each programmer accrues. Unfortunately, the sound is lightweight, and thus the reward feels light.


The gems convert to bouncing numbers on collection, providing a visual firework of sorts. The gem sounds are traditional, but the sound scoring effect is dated. Spyro may have very well helped pioneer the “zone of attraction” effect whereby a player “sucks in” currency around them.

Clash Royale

The audio design is top-notch, and so is the UX flow. Players always hit the main menu after receiving gold, so the connection between chest reward and gold balance increase is tight. The sounds indicated a TON of coins. Suddenly I’m Scrouge diving into a pile of copper coins. The only downside is seeing the gold form a straight line in the animation, thereby minimizing the total visual impact.

Runner-Up: Beatstar

Another slo-mo to admire near perfection

Beatstar’s UI oozes sex. It’s as if someone who exclusively works from home in red velvet bathrobes developed it. The UI art merges with animation; coins flip and spin, reflecting light when they enter a player’s balance. The artist again uses the motif of spinning objects with track stars, mimicking the opening of the Paramount “Mountain Credits.”

The stars have only gotten cooler.

Oh my, the music. Everything feels like it’s reverberating from a subwoofer, almost underlining the importance of the reward. Each currency gets a unique sound profile so players can differentiate on sound alone.

Winner: Brawl Stars

Surprise, surprise, it’s another Supercell win, but to be fair, Brawl Stars deserves it. The currency pauses, mid-animation, ensuring players admire it, before directly adding the currency to the power point bar. The amount of currency, in this case, 13 units, is the exact amount added to the power point bar. It’s impossible to miss as the currency spreads around the character portrait (“Poco”) rather than form a direct line, as we saw with Clash Royale.

The audio suggests chips instead of coins, a refreshing break, but the improvement of the power point bar suggests an almost score-like element.

Sense & Nonsense in Blockchain Gaming: Three Problems With Tokens

Mushroom Kingdom’s Gold Coin faired well against Hedgehog’s massive Ring devaluation.

Currency plays a peculiar role in economic activity. Classical economists are fond of claiming “money is a veil”; it abstracts away the underlying economic activity it helps coordinate. However, we know all too well that money is only a veil until it’s not. Monetary economics is justifiably a subdiscipline, so it makes sense for “tokenomics” to emerge as something similar to blockchain. And like early monetary economics, tokenomics finds itself suck in a strange mercantile stage of development wherein a token’s highest order is to appreciate rather than facilitate transactions. Something akin to increasing net exports and not letting money “leave the system.” But more specifically, modern tokenomics falls prey to three problems:

  1. Fixed Supply & Fixed Supply Schedule
  2. A Means, Not an End
  3. Make-Believe Ownership

Fixed Supply & Fixed Supply Schedule

Price stability builds trust because it is predictable. A fixed number of tokens and a fixed schedule in which those tokens enter circulation handcuffs the ability of monetary policy to respond to inflation or deflation. When stability collapses, so does trust; look no further than the recent wave of stablecoin disasters.

In the spirit of considering money as a veil, consider the effects of fixed supply and supply schedules on something like Magic the Gathering. In this parable, imagine Wizards of the Coast announcing a fixed number of card packs for the next set and a schedule to sell those very packs (ex., one-hundred packs for sale one week after release, three-hundred the week after). If there were many players and thus high demand, prices would be prohibitively high. Without the ability to purchase cards at a reasonable rate, players might churn to other games; a high price isn’t always the profit-maximizing price. On the flip side, too many packs for a given number of players could mean low prices. It’s hard to imagine Wizards of the Coast maximizing profit if they “minted” cards at the cost of production rather than exploiting their monopoly on card supply; P doesn’t equal MC outside of perfect competition.

Optimal monetary policy adjusts based on the conditions of growth and contraction, while most tokens prevent any such possibility. 

A Means, Not an End

Economy designers generally model currency as a medium between activities rather than an end to itself, and economists do the same. Instead, however, cryptocurrency white papers spend more time on token distribution and allocation than redemption, ignoring that a currency is only as valuable as it can purchase. 

Packy McCormick, an equally entertaining and informative writer, deep dives into the business models of start-ups in his weekly newsletter, Not Boring. In Braintrust: Fighting Capitalism with Capitalism, he chronicles the model of Braintrust, a talent platform. Late into McCormick’s explanation, he documents the cryptocurrency “twist” of Braintrust. By using and referring talent to the platform, users can earn tokens. It’s never clear, however, what these tokens gate or purchase. Users on the platform may price services in terms of the token, but they’d only do so if the token has purchasing power in real terms. Packy writes that Braintrust may offer “hints at future benefits for token holders; these might be things like educational content, free software, or coaching.” If so, the token’s price reflects the value of these services. I find it excruciatingly difficult to believe these services are worth much, so, in turn, the token shouldn’t be worth much. Starting a fiat currency from the ground up is a daunting task, but the most important precept of any token-backed project should be to grow demand for assets priced in the token.

Blockchain games do better here by exclusively first listing goods in terms of the game’s tokens; the token’s price reflects the demand for these goods. In the case of Braintrust, the token’s price reflects a future expectation that users or the firms will find a use for the token. Rather than composing a minority of a given whitepaper, explaining why there’ll be demand for assets priced in the token should be the analysis.

Make-Believe Ownership

A stock represents both a governance right and a claim on dividend payments from a firm. More recently, markets segmented governance rights between Class A and B shares. B shares vote on governance issues while class A shares do not. Most blockchain games took note and immediately segmented governance rights into separate a token altogether. In this way, there is some sense of ownership. But so much of this token class stands on shaky legal grounds. Are blockchain governance votes legally binding? Over what issues do token holders have autonomy? Can they fire a CEO? Increase a token’s supply? Again, the entire issue of ownership is murky.

On the other hand, no form of token entitles an owner to dividends. If it did, tokens would fail to pass the Howey Test and be subject to SEC regulation. As mentioned above, a token’s current price represents present and future expected demand for the assets redeemable by the token. This is a wildly different value proposition from a traditional share which derives value as a claim to a stream of dividend payments. Far from “aligning incentives,” the different incentive structures result in different outcomes. Redemption incentivizes the price of the underlying assets to increase; this isn’t always in the best interest of the underlying product or service. However, dividends incentivize the growth of a firm’s profitability. Profit incentive finances and signals supply expansion. The supply expansion makes everyone better, whereas redemption results in something like what we see with the NIMBY’s homeowner movement. In translated terms, it might make sense for someone who holds a hypothetical governance token in Magic the Gathering to vote against issuing new packs of cards. It’s not hard to see why this would be destructive to the game.


As blockchain applications grow and fluctuate, monetary policy will increasingly come under a microscope. Vague regulatory guidance and short-run design decisions to build trust have forced awkward token design. Moving away from these constraints will produce sustainable applications while aligning incentives between token holders and users.

Questions From a Student

A truly fun part about being a Game Economist is that 3-4 times a year, you’ll get the odd Linkedin message from students wanting to do the same.

I did get back to him!

It’s incredibly gratifying to help set people on the right track, given I was asking for the same help years ago. There’s so little on game economics it forces aspiring Economists to cold-call people with the title on Linkedin. This blog’s mission is to grow the conversation and those participating in it.

Along these lines, a student interviewed a fellow Game Economist for their master’s thesis. They shared the questions with me, and they were a lot of fun, so I’m reposting them here with permission.

What would you say is the biggest difference between the virtual economy in MMOs and the real economy?

Let me talk about virtual economies more broadly. In some sense, there’s no invisible hand in virtual economies. A virtual economy does not exist without a central institution that creates it. A designer needs to craft each inch of a virtual economy and how it functions.

In the real world, the environment is exogenous – a given, with each agent optimizing around his or her utility preferences. An agent is still optimizing around their utility preferences in a virtual world, something we have ample empirical evidence for (thank you, Edward Castronova!).

If game designers were to design the real world, they could alleviate things like hunger instantly. But a game-developed world wouldn’t mean a lack of pain or difficulty. On the other hand, we observe optimal flow state comes from overcoming challenges.

If we were to think about MMOs versus other virtual economies specifically, it’s the prevalence of player-to-player trade-in MMOs. This gives rise to floating prices facilitated via auction houses and provides a whole new dimension of engagement.  

Why do you think players value virtual goods more than real ones?

I can’t entirely agree with the premise of the question. The same Magic the Gathering card will command a higher price in physical than digital form. This will shift as Wizards of the Coast brings more events online than offline (i.e., the Pro Tour) and expands their online offering (Cube Draft! Commander!).

What type of goods is the most desired in MMOs and why? (Functional, hedonic, social)

Done correctly, whichever goods the institution incentivizes players to desire the most. A game where I could not see other players’ cosmetics would probably sell fewer cosmetics than a story-based DLC model, ala Destiny. Empirically, when I observe most MMOs, vertical progression or gameplay affecting items are desired the most—progression gates content that arranges a social hierarchy.

How is a competition created in games like WoW, FFXIV, or Lost Ark?

There’s the meta-layer of progression mentioned above, which adds a competitive element to the social hierarchy. Progression provides straightforward UX to “move ahead”; it’s incredibly meritocratic or at least “time-o-cratic” in many ways. It’s unclear how Lindsey Lohan moves up the social ladder at her high school in Mean Girls. In MMOs, the answer is clear: spend more time grinding!

Some MMOs have dipped into real-time combat-based elements like Alteric Valley in WoW or arena’s in Lost Ark. This re-arranges the social hierarchy to not depend on time but on “twitch skill” with a decent helping of planning. What equipment and skills players enter the Valley or arena with are dependent not only on time spent grinding but also on the planning players undertake on skill tree choice and gear equipment.

Why do you think some players rather spend money on buying an already leveled-up account instead of playing the game themselves?

Sometimes the Wikipedia article is better than the actual movie. Buying high-level characters let spenders jump straight to the top of the hierarchy. They may be missing out on the “experience,” but everyone has a soft spot for shortcuts. 

Would you say that high-level players play a role in making new players buy the virtual currency in games?

It depends, again, on the institutions the designer has created and what that institution incentivizes. The more social matters, the more high-level players probably play a role in monetization. But a game like Candy Crush has much less social. If you were to remove Facebook Connect from Candy Crush, I don’t like revenue would change much in an A/B test. I love Gardenscapes, but some players on level 1,000 do not change my propensity to spend as a new player.

How can someone create a fun virtual economy for players when economics is one of the most boring studies?

I could not disagree more! Economics is the most riveting social science out there. Economists commonly refer to “the set of glasses” the discipline grants after careful and dedicated study. The economic model helps me organize and think systemically about my world. There’s a satisfaction in the ability to take a random observation and build a model of understanding around it. Something that was chaos becomes order.

The best Game Economist is someone who brings to bear the tools of economics on games. It’s what Gary Becker does for crime or Richard Posner for law.

What game has the best economy, in your opinion? 

I think of the best economies as ones that maximize the net present value of the game. Economies here don’t refer only to how many currencies a game has or the price of items. Economies also refer to things like the supply of content in a game. I have a couple of nominations: 

Valve’s Steam Marketplace

Valve deserves a lot of credit for bringing player-to-player trade to a broad scale. The auction house and UGC design have given huge revenue and engagements tails to the games that have adopted it. Valve’s titles continue to have strong engagement, including TF2, a 15-year-old game that survives on community rather than first-party content. 

Clash of Clans / 4x titles (Game of War)

Selling vertical and horizontal progression is expensive since creating supply is costly (i.e., new level cap, new MOBA character). Clash of Clans (CoC) monetizes based on timers for creating troops. CoC treats a given troop as consumable; a single troop has only one attack use before it must be re-generated. The hard currency players can spend on reducing the generation time for new troops is a nearly infinite depth sink. 4X games use a similar loop while adding on consumables like peace shields. The result is LTV in the seven figures. The lack of consumables and expensive card creation in Clash Royale has significantly harmed its long-term prospects.


Perhaps an odd choice here, but match-3 economies are well understood and tuned. Match-3 developers understand the “meta” of the genre: how do I optimize level difficulty against the speed at which I can create new levels? There’s beauty in the rigorous optimization problem, and it seems to be going well. Match-3 grabs 21% of U.S. iOS spend, with players approaching decade-long relationships with a single title. Candy Crush recently celebrated its 10,000th level.

Netflix Finds Its Game Nest With Single-Player, Not Live Service

Let the DK power run through you, Reed.

Netflix is seriously ramping its games division. As of February 2022, I scrapped ~25 game or game-related titles on Linkedin. Excluding Night School (+15) or Next Game (+125), Netflix Games probably approaches an internal headcount of ~50-60. With both studios, ~150-200 Netflix Game or Games related employees. At 14 titles, we’ve seen of things like Dungeon Dwarves and Krispee Street, highlighting small indie-based narrative adventures rather than big-budget AAA affairs. On the contrary, I’ve yet to see a pundit to suggest Netflix get involved in the recent game M&A spree. However, in an industry turning hard right on live service, Netflix is justified in turning left.

Sense & Nonsense in Blockchain Gaming: Autarky No More!

No one-handed economists found.

In 1989, political scientist Francis Fukuyama wrote an essay asking if we’ve reached The End of History? Often mischaracterized, the essay argues democracy and free markets represent the last evolution of political-economic systems. Fukuyama writes:

What we may be witnessing is not just the end of the Cold War or the passing of a particular period of post-war history; that is the end point of mankind’s ideological evolution and the universalization of Western liberal democracy as the final form of human government.

Blockchain may well represent game monetization’s End of History.

Sense & Nonsense in Blockchain Gaming: Is “True Ownership” Actually True?

Take a stroll through a blockchain game website – they are all lovely; remember that’s their UA funnel! – and a standard set of phrases appear: “ownership,” “true ownership,” “truly owning.”

Is everyone hiring the same marketing brand guy?

But blockchain warps the traditional meaning of ownership into a ship of Theseus problem; each blockchain-based game can define ownership in its context. Suddenly, ownership becomes a design space in itself, making it all that much more crucial to dissect and analyze.

There are three stylized notions worth exploring:

  1. Ownership versus Licensing
  2. Item Possession versus Key Possession
  3. Obligation to Honor

Sense & Non-sense in Blockchain Gaming: A Series

KittyCash, a proof of concept for blockchain gaming. | by KittyCash | Medium
Thousand-dollar jpeg files do make sense; trust me, I sell digital hats for a living.

Sorry readers, I caught the blockchain bug. When 30-person firms are getting $4.5B valuations, it’s time to pay attention, regardless of one’s priors. Everyone seems to have a Blockchain hottake, but I’ve found most to fall short of ruthlessly integrating the implications and design space of the technology. Blockchain players (who are also, by definition, investors) insist, at every turn, that it’s so obvious blockchain gaming is the future. Advocates frequently cite specific benefits – true ownership, play-to-earn, “aligning incentives between players and developers,” and decentralization. A smaller crowd expresses skepticism about what blockchain solves for gamers, and if blockchain has the implications advocates think it does. This mounts a normative and positive element to discussions of blockchain. On cue, Benedict Evans offered a measured assessment of the situation:

The Church of FOMO: Can It Stand?

Take communion only on 24-hour timers.

A good deal of odd and folk-lore design priors float around gaming; my two favorites are free hard currency and time-limited cosmetics predicated on FOMO or fear of missing out. The FOMO model suggests developers ought to stuff their game with time-limited content, once the timer is expired the content is gone forever (or for a long time – a year or more). I’ve argued paper-thin theory holds up free hard currency, but small revenue stakes drape it as a marginal issue, whereas the FOMO model has a far more significant impact on the bottom line. High-stakes decisions demand more substantial evidence than low-stakes decisions, and we don’t yet have one for the FOMO model beyond “Fortnite does it.” Is there a persuasive and substantial case for FOMO?
