Yeah, I love Kingdom Hearts, mainly because it's what got me into playing Final fantasy. The first few games are a bit weak on the story but still really enjoyable. They fixed that with 358/2 Days and Kingdom Hearts 2 though. It can be mildly childish at times, and other times serious to the point of tears. Definitely a worthy and fun series though. =)
Yeah, the new Kingdom Hearts game on the DS. It's called "Kingdom Hearts 358/2 Days". :P It's got the best graphics and story I've seen on a DS RPG in like, a long time, if ever.
