Yes, 360 has Halo. Yes, PS3 will have FFXIII. Good for both of them. But when you live with your gamer girlfriend, single player games don't go far, and obviously all those online games won't do much good either as only one of you can play at a time (unless they have online and splitscreen).
So, I'm planning on buying a PS3 or an Xbox 360 in the next 3-4 months. What console has the upper hand when it comes to offline multiplayer games, preferrably co-op games? I understand that there are looking to be a lot of them out this year, so I have hope that you guys might be able to fill me in. =]
EDIT: It might also be worth noting that we already have two very powerful PCs, so if the games are already released for Windows anyway then it's unlikely I will buy a console for that game.
