It seems so odd to me to hinge ones gaming decisions on the multiplayer possibilities. MP isn't even a blip on the radar when it comes to ME. To me they are single player games. I imagine the multiplayer is fun, but considering how much I suck at games in general, it would be a waste of time for me to even try it. Let alone the fact that by the time I get through a game, I am more than ready to move on to a new one.
I also don't get why someone would buy the same game for both consoles. That's just weird. I wish i had that kind of expendable cash.
