This is a weekend project that spiraled out of control. I was originally trying to get Claude to play a ROM of the SNES SimCity.

Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance!

Building on the concept of generative agents and the success of c.ai, we created Simtown.ai, a 2D NPC simulation where each NPC leverages OpenAI APIs to plan, act, reflect, and adapt. The gameplay is dynamic and immersive—NPCs can move, talk, and idle in scenarios like Harry Potter Town or perform role-specific actions such as voting, giving speeches, and listening in Election Town [https://app.simtown.ai/electiontown]. We’re currently working on features like saving and loading game states, allowing users to create their own NPCs, and enabling user-personas to evolve over…
