This may be a biased group to ask this to, but are the Kingdom Hearts games, honestly in your opinion, worth taking the time to play? A friend of mine really loves them but while watching gameplay and whatnot, they've never piqued my interest much. Is this just because they're one of those types of games that you have to be playing to enjoy? Basically, should I invest my time and money into these games? Are they worth it? Is there a particular one that I should play to see if I like them?
