It's easier for western sensibilities to be mortified by this, but i would contend that yeah, its no worse than something like Manhunt
Its equally easy to understand the sort of fascination that this would hold, since there's quite the market for this sort of thing floating about out there, especially on the other end of the pacific. I do find it more repugnant, despite the fact that i play MadWorld with some twisted joy of sticking a road sign through a man, then slicing him in half, and this game is pretty much as stylized as that one is (except for color)
Sin is sin, and we all have our own guilty pleasures
