The Starcraft series. An awesome game that works solo, with fritends or with strangers. And it has a great customization/modification posibilities so it's easy to find something new to do if you got bored at one map.
I kinda hate the CS graphics. I love Crysis 2 multiplayer, tons of eye candy, + weapons, gizmos. I think any game that allows players to talk crap against each other on multiplayer is bound to become pretty addictive.
