I'd say give inFamous a chance. I didn't warm to it the first time I tried it, but when I got it for free during the whole "lol credit cardz" fiasco I gave it another shot and really enjoyed it. It gets more "Crackdowny" the more powers you unlock. Festival of Blood is a really decent PSN game, too. Still have to go back and play inFamous 2.
Uncharted 1 - didn't care for it
Uncharted 2 - a genuinely great game, had fun all the way through, would like to go back and play again someday
Uncharted 3 - ugh, a chore
I like the Resistance games I've played. The first is butt-ugly and obviously rushed for launch. I think I'm the only person on this forum who liked R2, to me it was a big stupid set piece SyFy channel movie, which is exactly what I was looking for. Haven't played R3 yet, but I've heard good comments (other than the campaign being really short).
LBP - Floaty jumping kills it for me, although I keep trying to like it with each new game in the series. Here's the thing, though - even with the shitty physics it's still a lot of fun to play with other people, everyone slapping each other around and just goofing off. If you're going to try it get LBP2, it improves a lot of gripes I had about the first one (except the jumping, but they pad around it by introducing new movement mechanics).
