I find Chess to be my favorite go-to game because it is the perfect game if you don't have a lot of time. I primarily play correspondence chess with a 10-14 day per move time control. I rarely (if ever) actually take that many days to make a move, but it is nice to have that time cushion for when things get busy. CC is great because there never is any pressure to "get in a turn."
If somebody is interested in getting back into chess, I recommend Chess.com. It has free and pay accounts and offers the most comprehensive chess experience currently on the web (news, blogs, correspondence chess, real time chess, 960 chess, Chess TV, and on and on and on). If anybody wants to play some correspondence chess over there (again, 10-14 day TC), just let me know. If there is enough interest, I could even organize a tourney (how about an Elemental tourney? ? With a 10-14 day TC, the tourney should finish just in time for the game's release! ).
BTW: Anand won today's game! Woot! Woot! Score: 1-1
