So basically, what's your favorite game that you've ever played multiplayer online with. Doesn't have to be the best game ever, but what was your one game where you had the most fun with in terms of online multiplayer. For me, it was Alien vs. Predator 2. The game modes were revolutionary, the action was smooth, weapons were cool, the different races made a new experience everytime, and it was just so much damn fun. Its still the most fun I've had.
