there is nothing wrong with U2 sp,i can assure you of that,
the shooter games will specialise into squad/story online games like mag,no doubt about that,and you have the mmo's...co-op campaigns are great
personally i want to play tomb raider on my own thanks not with a bunch of idiots,and when the network goes down,people will need SP's again
personally i'm waiting for the console online RPG,which you can basically play forever and live in that world,consantly getting updated and going off with your party on quests,yes i know i am a nerd but i don't care,no guns in my worlds just finely crafted handmade weapons and magic
