A Claude Code test built a 3D fantasy game base
Claude Code and Tesana were used to build an early base for a 3D medieval fantasy game. The work took about 39 prompts, two days of back-and-forth changes, and about $90 in so far. Opus 4.6 was the main code model, with some GLM also used.
Tesana’s muranyi-3 was used as the game model. The current build includes a mountain plain, a distant castle, a purple hooded wizard, and a movement system where the camera direction and walking direction can work separately. It is not a finished game yet.
It still needs the main game loop, combat, and more working features. The workflow started with 3 to 4 prompts to plan the core idea, then continued by refining , world details, and pieces with AI.
