Why I started A2G

I believe that one day games will come alive through AI.

Not as a gimmick, and not by replacing the people who design them — but as characters that notice what you do, remember it, and answer with intent instead of a script. Today almost every enemy, companion and townsperson is a hand-written state machine. Designers spend weeks wiring branches that players see through in minutes, and thousands of existing games will never get that attention again.

Models can already make good, fast, typed decisions. What is missing is a safe, boring, repeatable way to connect them to real games: one that keeps the game in charge, never breaks when the network does, makes cost predictable, and lets you see exactly what happened and why. That is what A2G is for.

I want A2G to be:

• Open — a protocol anyone can implement, for any engine and any model.
• Respectful of games — the game stays authoritative; its original behavior is always the fallback.
• Practical — measured in integration hours, latency and dollars, not demos.
• A path to shipping — use large models while you build, then ship a small local policy trained on their decisions.

A2G is at an early stage: one game integrated end to end, and a lot still to prove. If you build games, engines or decision models and this resonates, I would love to hear from you.
