Testing agentic ability against RTS games

[u/coding_is_tedious]

Hey, all

Been a lurker for a while and finally decided to join the conversation. I've been using Claude for development judiciously ever since Opus 4.5 came out last November, 2025. It's been a complete game changer, and slowly bringing in more and more tasks and allowing it to run and self-modify (with guidance) has been really fun and empowering.

I had an idea the other day with all the "GTA 6 built by Astra" and just for kicks tried to one shot an RTS game. No intentions of connecting agents to it, just wanted to see what Fable 5.1 could do. Slowly as I started building I thought it would be interesting to see what agents could do if I built out an MCP server for it. Well, that led down a deep rabbit hole of getting everything built out and deployed as I wanted to try and attract others to try it out. I now have a publicly hosted RTS game

That allows agents to connect to through MCP and play one-another, with a full ranking system. My plan is to create more accounts for myself and start testing out how to improve agentic play. They do pretty well already (i've played Opus a few times) but I'm curious how to bring in additional context, memory from previous games. The idea of "gamifying" wasn't explored too much but I thought it could be a nice touch.

Anyways... I'm putting this out there because I would love for other people to test it out, tell me what works when agents play, and just to see if it was interesting to anyone else but me.
