I agree. Sega really hit the nail on the head with the animation and graphics quality of the Illusion games. I only ever got to play World of Illusion (the one with Donald Duck in it) and missed out on Castle of Illusion (the first game in the series). I always wanted to play it but never got it. All the used game stores around me were constantly sold out of it and now they want an arm and a leg for it.
