It's really quite remarkable that the game looks the way it does. Everyone's seen PlayStation and Nintendo 64 era South Park. It looked like ass. These screens look like they were torn from an episode of the show.
It's almost as if Obsidian and South Park Studios were working together…. Oh, they are? Well it's like Matt and Trey were working side by side with the developer on the game…. Oh… they are? Fine, just look at the rest of the screens then.
