Just beat this game about 15 minutes ago...
I will say it is one fun game, but it is without a doubt the most fucked up game I have ever played in my life. The storyline is the most original I have ever really witnessed, and the characters are nuts. I have to say I thoroughly enjoyed this game. I just found out that the sequel is coming out in a little over a week too so I plan on picking it up.
I would say that if you are old enough and have a Wii to get this game because it was awesome. But seriously I do not recommend children playing this game as it is fucked up, gory, and an extremely mature storyline.
Here is the trailer for the sequel... yeah its really crazy...
