My biggest complaint is that the original sprite-based intro sequence has been completely replaced with the inferior animated one. I was hoping that both would be in there.
The lack of the original intro is regrettable, but I'd hardly consider the animated one inferior. Is it that you find the animated sequence itself objectionable, or just the fact that it replaced the original outright?
Also, I don't remember being able to switch characters at any time in the original -- I thought you had to be on a location you could save at to do that. Am I remembering things right or could you always do that?
Yeah, this feature is new for the DS. Does make the game somewhat easier, since you can just swap out any secondary character who's getting low on MP for one who's fully loaded. Makes getting through certain dungeons a breeze.
