I'm going through this now actually. Kingdom Hearts. I played it back when it was on PS2 and forgot a good 90% of it. I got a deal on the PS3 HD1.5 Final Mix version. Keep in mind I've never played 2 or any spin-offs, but I have seen half of 2 on youtube.
The jumping controls are awful, there's a ton of back-tracking, the combat is clumsy and slow, the combat MENU IN A REAL-TIME ENVIRONMENT is a terrible idea. "Time out Jafar, I gotta rummage around and get my healing item." Then there's the NPC party members who can't hold their own and blow through healing items, which is the same reason I stopped playing Rogue Galaxy (I'm sorry Mr. Blum, I tried.) The story is flat-out psychotic and I still question whether FF combined with Disney is a stupid idea or not. I usually think "Yeah, that could work, I'm willing to try it." then after about twenty minutes of playing it I'm just at the point where I'm internally screaming "This is the fucking stupidest idea ever, who in a boardroom mentioned this thinking they wouldn't be laughed out of their job?!"
But I WANNA LIKE IT. So far I like the Traverse Town theme. ...that's it.
