A part of me is really sceptical to this game, but I also know anything Trey and Matt touches turns to gold. Hopefully this game can bring the funny, and when Trey says they have been working on this for hours on end, and can't imagine it wont. It also looks like it's filled with tons of references to hardcore South Park fans.
I have high hopes for it as well. Especially considering Trey's and Matt's involvement in the project.
I love the South Park universe so much that i could probably still enjoy the original game for PS1 though.
