I have not yet beaten it, but there are loads of secret bosses and whatnot to do...I was trying the Weapon-type thing in Agrabah, and I can do it just fine up until about halfway through the fight, when it becomes a spinning hail of scything death that cuts me to ribbons within twenty seconds. (No spoilers asked for, I'm quite happy to be vivisected for the moment.) Not to mention that the music is wonderful and the graphics are just pure happy-making.
There is one spoiler I'd ask for, though - Maleficent, in dragon form, was actually pretty tough (I'm playing on Expert), so after beating her I ran right back to the save point and saved over my game without thinking. Is there anything crucial in that room where you fight her as a dragon that can't be got anywhere else, since it doesn't seem possibly to actually go back there?
