Full course: build a playable Unity fishing game with Claude Opus 5.5 in six steps

A detailed walkthrough builds a local Unity 6 fishing game (beach, pier, day/night cycle, real controls) with Claude Opus 5.5. Key lesson: never ask for "a fishing game" in one prompt. Steps: set up a URP project with the Unity plugin in Claude Code; greybox the level; add the core mechanic in one prompt and iterate by playing; generate models with Tripo, clean them in Blender with Opus, import as FBX; add lighting/water/FX/sound last; have Opus autopilot-playtest and list bugs before fixing. Commit after every working step so a bad prompt costs seconds.
