Not that great.
-The game will actually take you a decent amount of time, so it has a pretty good value. However, it's not like Zelda where you have a ton of stuff to do.
-All the voices from the show are here.
-A good variety of gameplay and various missions.
The Bad:
-Really lousy graphics and long, frequent loading times can be tough to swallow.
-Probably the easiest game I've ever played on Gamecube.
-Going back to the graphics...the worlds just feel empty. They're pretty big, but some of them just feel like ghost towns.
I would really only recommend this to Spongebob fans. Otherwise it has no flavor to make it unique.
