Indie Developer Builds GTA-Style Sandbox From Public Map Data
Charlie Chapman posted on X that he is developing a GTA-style game built from real, public-domain map data, aiming for a global-scale sandbox. The world has a weather system with rain, wind and storms, procedurally generated building interiors, and working vehicles including skateboards, snowboards, airplanes and rockets. A photo mode is implemented. Much of the work is done by AI: Chapman checks the progress of Claude Opus 5.5 on three Macs at home before bed and again the next day. The project has not been released.
