Mostly positive though. Unlike Thief and Castlevania LOS2, which were all the way from 3/10 to 9/10.
I'm playing it and if you're a South Park fan it is a hilarious. I'm sure someone who's no too familiar with South Park will still get a kick out of it but it is definitely made with the fans in mind "CHINPOKOMON!!" The most amazing part is how accurate the visuals are in representing the show. It really looks like you're playing an episode. At 14+ hours of gameplay it may as well be Season 18 re-purposed into a game.
Keep in mind, the game is explicit, as one would expect from anything "South Park." What's particularly funny is how much it pokes fun at gaming conventions:
Cartman: Clyde you have to wait your turn.
Clyde: That's lame.
Cartman: I know it's lame, Clyde, but that's how they did it in olden days so that's how we're going to fucking do it!
Cartman: Using your ability takes Power Points or PP for short.
Clyde: Heh heh "Pee Pee!"
Cartman: IF YOU HAVE A BETTER FUCKING NAME FOR IT THEN FUCKING SAY IT, CLYDE!
I'm enjoying it immensely.
