Free trophies can never be a bad thing!
But then I'd have Days contaminating my trophy list :x
I kid, I kid. Just find it weird that a glorified theater mode has trophies.
358/2 Days is included here because chronologically the series goes like this:
(Kingdom Hearts) -> (358/2 Days (Kingdom Hearts Re:Chain of Memories)) -> (Kingdom Hearts 2)
It makes sense story-wise to include it, but it doesn't make sense to completely remake 358/2 Days as a PS3 game, either.
