The better version of the game.
It was later ported to the SNES with a collection of other Mario games as "Super Mario All-Stars" in 1993. Finally in 2001 the game was ported to the GBA along with the original "Mario Bros" arcade game. I would actually consider this to be the better version of the original. There really is alot to offer in this game and it guarantees hours of fun like the Mario series is known for.
PROS:
-Enhanced visuals from the original game.
-Sharp control
-Wonderful music and sounds
-Characters have their own special skills
-Creative levels
-Mario Bros. arcade is a nice touch
CONS:
Overall, this game is really a must have for Mario fans and platform fans in general. Fans of the original game will most certainly not be dissapointed and newcomers will have alot to like in this game. I would also consider this as a definite must-have for your GBA collection.
