One of the best GBA games ever made. Easily one of the top Mario RPGs as well.
I just loved the story and characters. It was like the person who wrote this was on mushrooms because of how just plain wacky and silly it is. Nintendo really needs to take notes from this guy with later Mario games.
The Overworld was pretty cool, fast with no random battles. Plenty of jumping and puzzles in the mix as well.
The battles were sweet. I think my favorite combat system in any Mario RPG game. The bosses kept getting more and more epic. Such a great game, too bad the sequel was rather disappointing.
