I am a huge Kingdom Hearts fan!!!!! Ive played and beat all the ones that came out in North America including Birth by Sleep, 1, 2, Chain of Memories, 358/2 days, and re:coded.
By the way, Those of you that have missed Birth by Sleep missed a amazing experience with a spectacular story that dives right into Kingdom Hearts. Also a few cutscenes in the game are meant for die hard fans of the series. Oh and the Secret Ending will blow you away seeing it with your own eyes. So hopefully you get to play it soon.
