>One of the weird things about World of Warcraft was that there are (or were) folks who would sort of hang out in that world just to socialize and sometimes, perhaps, go out and kill some stuff. The 'hanging out' part was key, and I am convinced that if Blizzard could figure out a way for folks to sit down and play cards or checkers or something it would be popular.

Some of the most popular WoW UI mods were popcap-developed versions of Peggle and Bejeweled. Poker mods also were fairly popular.

Not sure if any of them still work, though.
