First thing's first. This review is for the GBA version, not the SNES version.

There are many words that describe this game: amazing, spectacular, superb, fantastic, and so on. All these words have something in common. They're all complimenting Super Mario World. I really don't think I've ever played a portable game better than Super Mario World. It's so entertaining. I could play the level 1 over and over again all day, and still not get bored. For all Wii, SNES, or GBA owners. This game is a must buy! Overall, this is one of the greatest games ever created, even to this day.
