Anyone interested in Ministers? It's chess on a 9x9 board with an extra queen. I've never played, but it looks most cool. I think it would be a nice addition to Brainking, and shouldn't be too much effort - from a technical standpoint, anyway. I'm not sure about the legal standpoint, as it is proprietary.

(I would hope the company wouldn't hate the publicity of having their game online.)
