Last week I built a 3D fortress-defense RTS in 90 mins. This morning (w/gpt5.3-codex-spark) I went after: impact, atmosphere, and agency. I hardened the Gemini AI Commander with a strict Intent Policy Gate. It analyzes without mutating state, previews without spending, and executes deterministically. No more confused AI voice spam, just phase-aware tactical execution. The magic isn't the model, it's all how we choose to use it.

Built a 3D fortress-defense RTS in ~90 mins with OpenAI Codex CLI (GPT-5.3 Codex High): React + Three.js/R3F + Rapier + Zustand. No hand-made assets: procedural GLBs + deterministic sim. Then I added AI Commander (Gemini Live voice) to plan + execute tactics in-game. 🎥👇
