I'm seriously quite open. Any of the variants discussed in the chess variant thread are possibilities for me. I'm actually probably most interested in Chess with Different Armies, but I'm up for anything. Even games that aren't in my thread but are on chessvariants.org are on my list. Let me know if something catches your fancy.

P.S. Probably my #2 pick would be Grand Chess, but if you're wanting something simpler, Self Eliminator is a possibility. I can point you to some software that would allow you to play all of these games, if you are interested.
