This editorial guide argues that in 2026 AI can produce a playable small browser game in an evening, citing Simon Willison's October 28 claim that building games that play well is "shockingly easy now" and Roblox's report of over 70,000 games published with its prompt-to-game tool. It details where AI still fails — long-session game logic, consistent art and animation, multiplayer and replays, performance on mid-range Android phones, and server-side score and payment checks — and summarizes Steam, Google Play, App Store and Telegram rules for AI-made games. It closes with guidance on when to DIY versus hire a studio, noting the studio's own starting prices from $8,000 to $25,000.
