u/SneakerHunterDev is developing an online multiplayer game modeled after GTA Online, with a core twist: every object in the game world — cars, buildings, weapons — is generated by players through prompts rather than hand-crafted by a development team. The result is a shared, persistent world built entirely from player-submitted creations, which the developer describes as slowly evolving into "an actual living world."
