## The idea

An app that lets you build walkable 3D worlds; choose to design each building. **Comp:** Roblox Studio, Decentraland, Spatial, Horizon Worlds, Promethean AI. **Wedge:** AI-assisted building — but Roblox/Spatial own the install base.

## Score reasoning

Feasibility — 3/10: Game-engine complexity vs Roblox/Spatial install base.
Best bet: Game-engine complexity vs Roblox/Spatial install base.
