If you ever saw a South Park episode you will know how this game is. It uses many reference from the cartoon, although the story is original. Two kingdoms, fighting for the Stick of Truth, humans and elves.
I didn't like that the player can't choose the character's gender, besides that there ar many options. Plus you can choose class and name, but name doesn't really matter since Cartman will call you Douchebag anyway.
The combat is turn based, and can use ranged, melee, or special ability plus items, like in most RPGs. There are many quests and sidequests, plus collectibles, and many more things to explore.
I think if somebody even slightly loves South Park will like this game, and not to talk about fans.
