MAG

Mag

Based on Demo experiences i would say LBP but i have never played either of the games in released forms.

LBP for sure, there are just so many things that are done with that game, and playing with friends is beyond awesome you can literally kill hours doing that crap.

uh....HRain if you want to step into something different.

I dont think anybody played LBP past first week anyway.

Depends. LBP has local play (which is really fun to play, and I haven't met anyone so far who didn't enjoy it. Even people who don't normally game), and there is a lot of content in that game, certainly recommendable.

I haven't really played MAG though, so I can't comment on that.

if u like play, create, share then pick LBP
if u like play, destroy, not share then pick MAG

Depends what you prefer, if you like platformer games, where you can create and share your own custom level, and play them all with other players go for LBP (it's like mario but better!!)
Or if you are into tactical shooters - then MAG is for you, however I must warn you MAG may not be your thing as it is not like COD, you actually have to co-operate with other players to actually enjoy the game properly.

i did.

But i prefer MAG
