A hands-on test of OpenAI’s GPT-6 Astra building complete games in Unreal Engine. The creator prompts the model to recreate Super Mario, Subway Surfers, Counter‑Strike, Minecraft and GTA, forcing it to generate code, assets, maps, and UI (with and without using external resources) to evaluate AI-driven game development capabilities and limitations.
– Setup: Uses GPT‑6 Astra via Codex with Unreal Engine 5 and Blender so the model can produce code, 3D assets, maps, and UI end-to-end.
– Recreations: One-to-one remakes of Super Mario, Subway Surfers, Counter‑Strike and Minecraft; some builds relied on discovered open-source clones, others were created from scratch.
– Limitations: Playable but unpolished: visual glitches, placeholder assets, audio differences and occasional mechanics bugs require iterative prompting to refine.
– Highlights: The model produced menus, procedural infinite maps, exportable Blender assets and working gameplay within minutes, demonstrating rapid prototyping potential.
Quotes:
I can’t really tell the difference between this and the real game.
GPT Astra actually cheated in building this.
Five sentences to GPT‑6 Astra and we had a functioning 3D game.
