You made a game. gg. Turns a web game into a short trailer played live in its own engine: Claude writes the film, opens it in a studio for you to tweak, and exports the mp4 with its music, poster and share copy. Use when someone says \"/gg\" or \"let's gg this\", or asks for a trailer, teaser, launch video, gameplay montage, \"coming soon\" clip, end card or logo reveal for a web game (three.js, React Three Fiber, canvas, Phaser, DOM). Also for launch films of non-game web projects (component libraries, apps, dev tools), where the engine is the real product UI. Also use to add or fix a take in a trailer studio.
