If you happen to have a Gamecube, and if you have 3 friends who enjoy playing video games with you...go rent Four Swords. It's part of the Zelda "series", but, is ideally played multiplayer. My husband and I have been playing it with another couple we are friends with and HOLY CRAP. It's so much fun. It's cooperative, yet competitive at the same time. Oh, and uh...you have to have four Game Boy Advances too, for the controllers. ><
Anyways, just my geekery recommendation for the moment.
