One of my Favorite Games of all Time.
This game is very,very fun and if you have not played it yet. Then stop reading and take out your GameCube and play one of the most charming games ever made. Part of what i love about this game is its simplicity, there is still plenty of Badges (different pieces of loot that affect various things) and items to collect but what it comes down to is using the right moves at the right time.
Now as for the story there's not much to it but obviously more than the average Mario game Sir Grodus takes Princess Peach to THE MOON and you have to reach her before something bad or something.
All the while you're leveling up, meeting new companions, beating bosses and talking to some quick-witted civilians.
This game is a blast and one that i go back to every year.
(In case you didn't get the hint i like this game and you should play it)
