While I do kinda like the Kingdom Hearts series, I find it far too simple. The combat system is really just a button masher, and not a very rewarding one, at that. Plus, the story is so confused with itself, adding new things that were never a part of the games to begin with. Like the whole
Roxas is technically Ventus' nobody, since he's actually Ventus' heart trapped inside Sora's, and it really makes no sense whatsoever.
The whole story is a mess of rewrites or additions. And then they tell us Kingdom Hearts 3 (though technically it would be the 8th game, but whatever) is going to end the "Xehanort Saga." They make it sound like they're going to continue the franchise after this, which makes no sense. If Xehanort finally dies for good, the true antagonist of the series is gone. There's no need to continue after it.
I realize now that I'm just ranting, so I'll stop.
