Little Big Planet VS. MAG

[bobobologna]

Well, one is a platformer with a level editor built in.

The other is a large scale tactical shooter.

I don't really see why you need us to tell you which game to get. I could understand asking which game to get between BF: BC2, COD: MW2 and MAG, but to ask between two completely different games when we have no idea what your gaming tastes are is weird. Little Big Planet does have a demo though, so you can give that a shot and see if you like it. I don't think MAG has a demo.
