LBP is great for creativity, but the actual gameplay is shallow. Sackboy cant double jump, backflip, attack, etc.
Why would you need to be able to do those things to enjoy that game? :-/
You can't "attack" in mario land either. You jump on things or you throw things. both of which have already been shown in LBP. And there's also a plane-shooter level in LBP, so "attacking" is also possible. Weird reasons to downplay LBP.
@elendar, I did mention those, they fall into the "more of the same" category i mentioned above,
And MGS4 isn't just an elaboration and expansion (albeit good one) of what MGS3 / 2 / 1 had? right...
