Forget Hours Logged: The Case for Judging Games by How Long You'll *Want* to Play Them

The word "Billion" in our name gets us funny looks sometimes. It sounds like a valuation, a download count, a revenue target. We mean something else by it — and this piece is our attempt to explain what.

The Metrics We Use Measure the Wrong Thing

The game industry runs on two numbers: hours played and money spent. Engagement and revenue. Everything downstream — battle passes, daily login bonuses, FOMO events, the entire live-service apparatus — exists to push those two numbers up.

But notice what neither number actually tells you: whether the player enjoyed any of it. A slot machine produces enormous engagement. A treadmill at gunpoint produces enormous engagement. Hours logged can just as easily measure captivity as affection.

Here's the thought experiment: what if we measured games by desired play instead of actual play? Not how long you played, but how many times, across your whole life, you'd genuinely want to start it again?

Call it the Billion-Play Test. Can a game rack up a lifetime of willing returns — a billion, if you're ambitious?

What Desired Replays Would Change

Run the current industry through this metric and things get uncomfortable fast. The live-service game you logged 400 hours in but haven't touched since the season pass ended? Desired replays: maybe two. The 90-hour open world you completed once out of sunk-cost obligation? One, and it was grudging.

Meanwhile, the games that score highest on desired replays are often small. A five-minute roguelike run. A puzzle box you return to every autumn. The game you boot up not because a notification told you to, but because you felt like it — and the feeling came back, unprompted, for a decade.

Desired replay is the purest signal of love a game can generate. It can't be farmed with FOMO, because FOMO produces reluctant play, not wanting. It can't be stretched with padding, because padding lowers the desire to return. It's nearly impossible to fake.

Japan Already Designs This Way

Here's what's interesting: a lot of Japanese design philosophy already optimizes for desired replays, whether or not anyone's named the metric.

Shikata ga nai — "it can't be helped" — is the cultural acceptance of impermanence. Games built on this sensibility don't fight the fact that players leave. They make leaving painless, which paradoxically makes coming back easy. No streaks to break, no guilt engine running in the background. You return because nothing about returning costs you anything.

Seasonal release rhythms do something similar. Japanese games and toys have long leaned into seasonal events — summer festivals, New Year's, cherry blossom windows — that come and go and come back. The content isn't gone forever when the season ends; it's resting. Desire rebuilds naturally instead of being manufactured through artificial scarcity.

And the short-form tradition — the arcade run, the fifteen-minute commute game, the single puzzle a day — treats a session as a complete experience rather than a fraction of a grind. A complete experience can be wanted again in full. A fraction of a grind can only be resumed.

The Challenge to American Developers

So here's the gauntlet we're throwing: build the first game designed explicitly for the Billion-Play Test. A game whose success metric is how many times a player chooses it over a lifetime — measured honestly, with the reluctance filtered out.

That means no daily streaks. No fear-of-missing-out. No engagement hooks that convert anxiety into logins. It means designing a game that's pleasant to leave and delightful to return to, that gets better with each revisit the way a favorite album does, that a player in 2050 might boot up on a whim the way we still play Tetris today.

Tetris, for what it's worth, is probably the only game that's already passed the Billion-Play Test. Forty years old, no live service, no battle pass, and people still want it. That's the bar.

Hours played will always be easy to measure. But easy metrics built an industry that players are increasingly exhausted by. Wanting — genuine, unprompted, decades-long wanting — is harder to count and infinitely worth more.

That's the billion we're chasing. Not users. Returns.
