So, what are your favourites? Do you even own any? I don't have much in the way of multiplayer action... Mortal Kombat of course... and I have Need 4 Speed underground that I believe you can use to race your friends, but I think that's about it.

Some of my games have smaller multi-player parts added to the main single player 'career' or 'quest' type game, but that doesn't really count.
