Actually Yasumi Matsuno wrote Mad World, so I'm not surprised you like the characters and story. Mad World really is a better game than you would expect it to be but I feel the assessment and low rank is pretty accurate, the game is pretty much for low brow gore violence like what you would get from the good Mortal Kombat games.

I also agree with Pokemon, though you'll get a lot of hate for ranking it so low but since every game is essentially the same with just a few new mechanics added in, I'm not exactly feeling left out for not really pursuing the series like other people have. Its a good series but I feel it really depends if you can get behind what it offers, much like the Mega Man games which I do like despite being essentially the same game with each installment.
