When you said you played LBP, did you mean you are in the beta or you visited a friend that was in it? The reason I ask this is because I don't see the PS3 listed in your sig.
I was in the beta and I can tell you there is a difference between playing for an hour and a week. You should give it another chance if you only spent a brief amount of time on it. Playing/designing it with friends/gfs is such an amazing experience.
