Which game has the greatest online of all time, ever?

[Serenegoose]

Quake 3, in my opinion. Purest FPS action I've ever played, or seen played.

As in, so far in time, right? Then probably Left 4 dead 1 and 2, considering how much time ive clocked into both of them, and of course that they are both very fun.

Starcraft Broodwar, once they fix the custom game system, SC2 will be ahead.

I'll second Battlefield 1942. Very fun.

Among console games, I choose Left 4 Dead 2, of course.
