It would be awesome to have two interacting communities: AI experts building open source general game playing engines, and gaming fans writing pluggable rule specifications and UIs for popular games.

A bit of googling shows that there is a General Game Playing AI community with their own Game Description Language. I never really encountered them before, and the DeepMind paper does not cite them, either.

Last I looked, the GGP community is focused on perfect information games currently. I had the same thought, though.
