With the exception of Advance Wars and possibly Wario Ware Inc, I believe that Mario & Luigi: Superstar Saga is one of the very best games out there for the Gameboy Advance.
Of course, it stars Mario and Luigi on some big-time adventure. This time, they must stop the evil Cackletta from (you guessed it) taking over the Mushroom Kingdom, or something like that. You get to battle as both characters, jumping on and hammering your enemies. You can also use some cool special moves called Bros. Attacks, where both characters can team up to use one heck of an attack.
The game varies a lot. Each level if different, with different challenges to take on. As the game progresses, it gets harder and harder, but never frustrating. You will find yourself doing all sorts of things from spitting water to fighting dragons. The boss battles are unique and varied too.
It's really funny too. The cartoonish graphics and cartoonish characters provide great laughs. It includes many moments of psychical humor and silly jokes. The jokes aren't very memorable, but worth watching. One of the funniest ones was when Fawful says "I HAVE FURY!" However, the game is not for hardcore RPG fans. Mario & Luigi: Superstar Saga requires timing in it's attacks to pull of great feats. It uses little customization or leveling up. You don't buy new weapons or partners or anything like that.
Unless you are expecting a top-of-the-line RPG, you will be disappointed. But, if you are looking for a fun time, pick this one up...immediately! I wouldn't hesitate to recommend it.
10/10
Good: Funny, clever, silly, entertaining, and one of the best action-RPGS around
Bad: Not for hardcore RPG fans
Note: I think the DS sequel holds up more than the Advanced Wars and Wario Ware DS sequels
