Extremely disappointing. The idea itself, while perhaps not genius, is decent and could have led to a fun and unique sports game compilation. It just didn't. At all. Not even a little bit.
Console Obsession:
"Awful concept aside, Celebrity Sports Showdown isn't a bad game to spend a few hours with from time to time. The growing casual market could find that there's plenty to enjoy here, but it's hardly going to appease core gamers who have a diet of more substantial offerings. So as a part of the latter group it's a six, but if you're one of the former, perhaps add two points to the overall score. So a solid six it is from me then."
Pick up and play party games, seem to dominate the Wii. So with such a wide selection available you would think games companies would put extra effort into theirs to make it stand out.
This 'game' might have some value to those who enjoy seeing a Mii-Fergie playing watersports, masochists or the aforementioned menu fans. If you enjoy life, avoid it like the plague.
