GPT-6 Astra helped me build a playable jelly game in Unreal Engine. I also let it work on a separate 3D RPG without my playtesting—and those two projects changed how I think about getting useful results from AI. I show what the MattVidPro community is creating, walk through my jelly game’s physics and garden, and explore the autonomous RPG’s impressive details and rough edges. Then I share my experience using Astra in Codex, these are playable demos and personal observations. Huge thanks to Woosh, Guru, Godly and Brutus for the community creations featured here!
