A must-have for the gba!
It is not like most rpgs because you get a sense of action while playing. You start out with just jumping but you get more abilities as the game goes on. When you get a new ability you can use it in battle and on the map. The game takes place in a foreign country called Beanbean kingdom. The best thing about this game is the bros. attacks. Bros. attacks are basically combo attacks from Chrono Trigger except you must press buttons or the attack won't do as much damage. Also, the game is hilarious even though it is directed toward kids.
There really isn't anything bad about this game except that is is a bit too easy.
The sequels to this game are Mario and Luigi Partners in Time and Mario and Luigi Bower's Inside story.
If you own a gba you must get this game!
