Oh, I haven't wrote anything about it here?
An amazing game, I think this is exactly how a South Park game should look like. Strong storytelling, a whole lot of fan service and the original humour of the show. You feel the love Trey and Matt and the developers put into this, it is like a second South Park movie.
I liked the game mechanics as well, but it was too easy from a certain point. I played on middle and changed to hard later. The second thing I found very frustrating was that you can miss things (achievements, but even collectables).
But over all I am really in love with this game. My favorite parts were Canada and Mr. Slave

. But the ending was great as well. And so many nice little ideas in between.
I played the U.S. version on ps3, my cut German Steam version is still untouched.
