Purchased it on Friday, finished it sunday afternoon.
It's like final fantasy 7 + monkey island + more toilet humor than you can shake a stick (of truth) at = awesomeness.
I am not going to spoil anything, if you even remotely like south park then you need to play this game and preferably you will get the pc version as then it isn't censored to shit.
EPIC GAME! I award it 8 and a half kuriks.
Eagerly awaiting the dlc.
