Just now looking over the trophy list, and there's some odd ones like playing after 9pm (no problem) and before 9am, as well as the trophy for playing every day of the week. I do like the trophy for slapping 2 people at once.
All that being said, though, I like them a lot more than LBP1's list. I never wanted to ace all of the levels, that would probably make me hate the game. Also, the create trophy was kind of daunting and lead to all that H4H bullshit.
On the bright side, it looks like a very likely platinum for me. The "hardest" ones seem to be the long term play trophies like spending 24 active hours in Create mode (not gonna cheat that), and playing a lot of LBP2 won't be a problem for me.
edit -Nevermind, there is a trophy for acing every level. Dang, I was hoping they wouldn't do that this time. Oh well.
