In agreement with JohnDernoncourt...
Get a life folks.
Multi-player is just an extension of gaming consoles. Player vs Player has always existed. The only "new" thing that has been introduced really is a "persistent world" such as EQ / WoW and others of that type to where the world keeps going even when you're not playing, and other players can play in your game world while you're not there.
The rest of it is just social jousting. such-n-such sucks.. such-n-other was first. you suck because game xyz sucks. etc..
