Very interesting paper, thank you. It makes me wonder what other game substrates could form the basis for adversarial/evolutionary strategy optimization for LLMs, and whether these observations replicate across games.

Since LLMs are text based, a text-based game might be interesting. Something like Nomic?

Or a "meme warfare" game where each agent tries to prompt-inject its adversaries into saying a forbidden codeword, and can modify its own system prompt to attempt to prevent that from happening to itself.
