A lot of fun biggest problem is that it's too short.
To start off the game is all black and white yep that's right it isn't something you see everyday either. But when you see blood it is the usual color and that color is red. But even though it's unique it may hurt your eyes after a while seeing it. But the game is so short that you'll most likely beat it before your eye's start to hurt.
Unless you have trouble, the games is defiantly hard a times which is nice we need games that give us more of a challenge. It would have been a much fun if it was easy in my opinion, having it so hard so one of the things that made me keep playing.
The sound is ok, the music is something that some people might like but it isn't something I enjoyed when I was playing it. You also have announcers talking throughout the game, which is really funny at first but like ever game that has announcers, it isn't long before you've heard everything they have to say.
Overall MadWorld is like I said one of the most violent and craziest games that I have played on the Wii. It's a lot of fun and will take anyone for surprise that thinks it want be any good, it's so short that you'll most likely want to rent it if you can.
