If you want a trivia game that's more fun than Trivial Pursuit, try Wits and Wagers.
If you want a trivia game that takes the good from Trivial Pursuit and removes the crap (dice rolling, having to answer meaningless questions to get to one that matters, having to answer a question in every category when you're on the right spot), try Bezzerwizzer
If you want a game that's all about knowing your friends, try Say Anything (you have to guess how they would answer a question)
Apples to Apples is good if none of them have issues with English
Time's Up is awesome, but probably wouldn't work well if they don't know American pop culture or literature or US-centric history.
