Sounds cool. To widen appeal it might be good to include other games. Checkers, maybe backgammon. And I'd really want to see lots of chess variants too, like fischerrandom, seirawan chess, etc.
That's a good idea. You can toss Go in there as well. I guess that would cause problems with high level quests though, because there isn't a good Go computer in the world.
Oh yes, definitely Go, how could I forget. I really wish I could find someone to play this with. I bought a board and stones a few years ago and have only used it a few times. But yeah I think this would be good with a few more games. Just so long as no card games are allowed. I hate the whole poker crowd.
Okay so - I was just off on my break for a brainstorming session with Xenien7 (a coworker) and we've come up with a lot of ideas, I'll post them in a moment.
