I just picked up Black Ops II on PC this weekend (since I left my Xbox at home). I have to say it's much easier to aim and play with a 360 controller. I guess you can play on the PC with a controller, but I think I'll end up getting it on either 360 or PS3.
How do you join a game with a friend on the PS3? It seems impossible. On Xbox all I'd have to do is invite to party and go...I guess I should've gotten it for 360 instead. There's literally no option to start a party or join a game with a friend
