Best movie license game I've ever played. I love it. The turn based RPG system fits so well with the animation. This is the game that south park fans deserve. I'll go over the positive aspects and the negative aspects.
-This game is incredibly funny. It's raunchy and dirty sense of humor fits me so well. I love it. However, if you are not into that kind of humor, this game will not appeal to you.
-The turned based combat would sound bad, and boring... But it actually has you involved. You don't just choose a move and then watch it play out. It's kind of like the Mario rpg games, where you have to put in some sort of actions to make a "Perfect" hit. The combat is also fairly fleshed out. There are status effects that can be inflicted on enemies. Also the unique ways each buddy can be used to suit your play style. You can even use the enviroment outside of combat using your abilities you get, such as your fart magic, and an anal alien probe. Skipping combat completely, but getting the experience.
-Plenty to explore, and has some replayability. Although I never completed it after doing it twice.
-It is creatively written. The story line is fantastic. Which it should be, being written by the developers of the show themself.
-Due to the kids larping, it makes some creative items. You can literally take a crap in a toilet, and throw it at an enemy to gross them out.
-The story line and all side missions can give you around... 20 hours, even more if you want to replay it.
The negative aspects are just me nit picking a bit, but some of these can be an issue for others.
-This game is for south park fans, and for people who are not easily offended. If you are not a south park fan? You might not enjoy this game, and not get most of the jokes.
-The game is too easy on the default difficulty, and even on hard mode, it can be easy. I've found myself never losing a single battle when you follow the story line.
-20 hours is a VERY short rpg game, when it ends, you just want more!!
