Suggestions for future Game Nights

Hey you! Yes, you! You play games, right? Online games? Perfect! Because as you know, we run a little program here called the GameSpot Community Game Night. (Example of tonight's Smash Bros Game Night here .) If you've never joined in on the fun, this is your chance to play online against both GameSpot users and staff. What we'd like to know is this: what games would you like to play against others online? What games on the horizon look fun? We'd love to hear your suggestions for future game nights if you feel there are any hidden gems we may have over looked.

And yes, we'll definitely be doing a GTA IV game night when that one comes out. 16 players causing random havoc in a full-scale GTA world? Yes please!
