A lot of people ask me how I build games.

Well, it's pretty simple and I call it "vibecoder dream"

Before going to bed, I give a simple game idea to Tripo CLI + Unreal CLI, then, using ORCA CLI, let Fable orchestrate everything at max effort, with 10+ Opus 5.5 agents running at high effort.

By the time I wake up, I usually have something like this.
