My boss is looking for a "take you're turn whenever" strategy game. What I mean is that one of the two players take a turn and then the other player can log in at any time and take a turn. It needs to be 2 player because he only wants to play with one friend. Basically either player can log in and see if it's their turn and then take it if it is.
It can be a commercial program or a free one. It doesn't have to have amazing graphics. I would prefer that it be a game that's on an online server rather than a direct connection (or at least the actual game in play is kept on the server).
Also, they're looking for something closer to rish, axis and allies, or command and conquer rather than worms.
Thanks for any suggestions you may have!
