South Park: The Stick of Truth has "authentic crappiness," serious roleplaying

Judging from this behind-the-scenes video, South Park: The Stick of Truth is everything you’d want from a true-to-the-source South Park game. (Minus Isaac Hayes, RIP.) There’s “authentic crappiness,” analogue fart controls, and wisecracks written by the creators of the show, Trey Parker and Matt Stone. But it’s also something you wouldn’t expect: an RPG with character development by Obsidian, the team behind heavy-hitters such as Fallout New Vegas and Neverwinter Knights 2. Does this mean South Park is taking back those jabs it made at Warcraft?
