South Park RPG - Preview @ Capsule Computers
Capsule Computers has a preview for this game. A quote on the plot:
The general plot of South Park: The Stick of Truth is that the entire town of South Park has been swept up in yet another craze, this time live-action role playing and in classic South Park fashion, it all gets unbelievably out of control. The LARPing plot lends itself well to an RPG game and it seems to work wonders here in the world of South Park in which it pokes affectionate fun at the genre itself.
