This game is great,

The universe of the series is here, references in every sense, humor crying laughing, effective scenario
And vostfr? I think the best way to make the game, watching south park in vostfr (which I think is 10 times funnier in French, jokes numbers of poorly translated or impossible to translate, unique voice cartman English).

In short, if you watch in the south park vostfr, throw at you !!
For allergy to English, so take really are a fan, you will still have a good time.
For others, it is a basic rpg, go your way.
