A 23-year-old makes $11,000 a month building full arcade games from a single AI prompt he doesn't design games. he describes them. he points Claude Opus 5 at one instruction: -> "build a playable Rocket League in the browser, make the assets, wire the game loop, check for errors until it runs" -> and it ships a finished game on localhost. he's done it with a Rocket League clone, a Stardew-style farm, a Plants vs Zombies. then he turns the clips and the games into caps: - the "one prompt built this entire game" videos -> millions of views, sponsor slots from AI tools - the games dropped on web-game portals -> paid per thousand plays, no store, no publisher - a prompt pack + "build a game in an afternoon" guide -> sold to everyone who wants in - playable-ad mini-games for brands -> delivered in a day, near-100% margin $11,000 a month, and the hardest part was writing one good paragraph. he didn't learn Unity. he learned to describe a game precisely enough that a model builds it for him.
