Unlike many games out right now, this South Park game is fun. It's simplicity has a lot to do with that. It combine's walking around and exploring in a manner similar to Monkey Island, with the classic RPG fights of old Final Fantasy games.
Combined in South Park's theme, this game is a good time. As an older gamer, there are some childish parts I could do without (like the amount of gas jokes), but in the end (no pun intended) the clever humor outweighs the lowbrow.
I've played the other South Park games (dating back to the 90's) and this is the first that made you feel like you are really in the show.
I'm close to beating it, and it seems a little short, but given they don't have the budget someone like Square has, it makes sense. Hopefully this will open the door to bigger and better South Park games.
