Story-wise?So what order do i play these in story wise? And is kingdom hearts re:coded just different story version of KH1 on the ps2?
BBS, KH1, 358/2 Days/COM, KH2, Coded, DDD
358/2 starts before COM, runs concurrently with it, and ends a bit after COM ends.
Just play them in release date order and you're fine. Just because a game is a prequel doesn't mean it isn't set up to reveal information that's been set up in the previous release.
