I've asked a few people about this and have received conflicting answers - I'm hoping someone can definitively answer this question.
Can you continue to work towards finishing challenges (both general and area specific although I'm mostly interested in whether the level challenges are retained) once you beat the game? I can't imagine that they would set these back to zero after starting the second playthrough (particularly as some of them are so freakin random) but I thought I'd confirm before making the jump to PT2.
