As someone who's only aware of the Kingdom Hearts series, which blends Square Enix style action-RPG storytelling with the world of Disney, the fascinating part of it all is that unless you've played it, well, it seems incomprehensible. Case in point, the new Kingdom Hearts - The Story So Far collection coming to PlayStation 4 on March 29 in Australia.
Which really seems to stretch the concept of game and sequel. I mean, look at this list of entries and stuff included.
KINGDOM HEARTS HD 1.5+2.5 ReMIX
- KINGDOM HEARTS FINAL MIX
- KINGDOM HEARTS Re:Chain of Memories
- KINGDOM HEARTS 358/2 Days (HD Remastered cinematics)
- KINGDOM HEARTS II FINAL MIX
- KINGDOM HEARTS Birth by Sleep Final MIX
- KINGDOM HEARTS Re:coded (HD Remastered cinematics)
KINGDOM HEARTS HD 2.8 FINAL CHAPTER PROLOGUE
- KINGDOM HEARTS Dream Drop Distance HD
- KINGDOM HEARTS 0.2 Birth by Sleep –A fragmentary passage–
- KINGDOM HEARTS χ Back Cover (movie)
Apparently playing and watching all of that will help you "catch up on the story leading up to KINGDOM HEARTS III", which is out now.
