I have read Alex Navarro's review of this game here on Giant Bomb and let me say; He is way to hard on this game. It's a platform game, with a story about revenge and a quest for save files.
If you don't like South Park, you will not like this game. If you do like South Park, you would probably love it. It got plenty of references to the series, a style that fits the show and a fun enough gameplay.
The forced co-op of the game was a big mistake, but GOOD NEWS they removed that in an update.
Great entertaining game for South Park fans. Anyone else would probably not enjoyed it or see the point of it.
