I've come to like playing Mahjong when playing it at the library. I'm still trying to get a grasp on it since I don't play very often except maybe once a month or something when the library has the programs, but it's still pretty fun. And it's actually the legitimate way to play Mahjong, not the Solitaire version, which is cool.

I've also played Monopoly, which takes forever, Sorry (which took me a minute to understand), and a variety of other board games with some of my friends and/or family. The one I've come to hate the most is probably Risk. Lost that game the first time I played, & I haven't liked it since. xD Plus we'd be playing for hours, even after I'd lost.
