Without a doubt the best game I've ever played. Everything about this game is top notch from its writing to its unique areas, amazing soundtrack, fun visuals, a really nice take on the classic Mario story, coupled with one of the coolest gimmicks a video game could have. Playing nearly half the game with Bowser was and still is something completely unique to this masterpiece. The battle system is one of the best I've seen in an RPG, second only to its sequel, Mario & Luigi: Dream Team. It truly is the best game of all time.
