...then maybe Mah Jong (if that can count as a board game) and Mille Borne (if that can count as a board game) and Monopoly (which is a board game). I have a hard time finding enough people to play long enough to get out Monopoly.
Have you seen or heard of Monopoly playing cards? It's the most fun I had playing any sort of game in quite awhile. I forget exactly what it's called, but I'm sure it's on the official website.
