Beat Batman a couple of days ago and went back to find all the trophies I missed, Popped all balloons, broke all joker teeth, destroyed all cameras solved all riddles and completed the riddler side quest. Only thing I have left to do is the physical challenges. I was gonna do another play through but I didn't notice until after I beat the main game that I was playing on easy by accident. If I was playing on normal or hard i would replay in the plus mode to go for other trophies. Maybe once I beat Uncharted 3, MW3, AC Revelations and Skyrim I'll do a replay.
