I'm suspect to say it 'cause I'm a really fan of this cartoon (you can see it by name :p) but man, what a good game. This game fixed all the "The stick of truth" flaws (such as the poor combat system and quick campaign) with a very cool and funny campaign (less funny than stick, but still funny), a well made combat system that is pure tactic in high difficulties and nice characters with all good personalities (except toolshed).
I REALLY recommend you play this game sometime in your life, probably one of the best games I've played in my life. Just put the advice that the humor used in the game is kinda..."strong", just like south park is. Worth every cent I paid.
Here is some cool screenshots I took (there are spoilers)
But given the time of year, this is the perfect time to watch:

He just appear to take a selfie and go away, just like Jesus.
