Which do you play on consoles? Multiplayer or single player?
Also, if you don't mind, which console do you play MP/SP on?
(No console wars, please)
EDIT: I tend to play multiplayer all the time on the Xbox 360. I have no idea what the ecosystem for multiplayer is like on the PSN, so when I get the PS4 later this year it'll be interesting to see all the little nuances and see how big multiplayer is on the dark side.
