This game looks pretty dire imho. I'm not a fan of gore porn like Hostel, Saw or any of that crap so a gore porn game does even less for me. At least when doing crazy rampages in games like GTA it's done purely because 1) it can be but it's not the goal of the game or 2) because of some minor plot point in a grander better storyline which involves more than simply killing everyone.
It mirrors the same effect of that of a horror movie, in my opinion. There are very few games that allow you to take control of a psychopath and murder people for the sake of murder (as far as we know about the gameplay), but my argument would be as follows; How is this any different to watching a horror movie?
If people feel that others wont have the mental capacity to play this game without going on a mass murder spree themselves, I hate to tell you that anyone that does, has other problems that need to seriously be adressed. Video games dont breed violence, hate and mental disorders breed violence. I am intruiged by the design of the game (not so much the gameplay) since it appears to take some ques from the horror/gore genre, especially with its executions.
I dont think this is a game though that will be praised, due to its controversial nature. The gaming industry has come so far in terms of these very issues, and this game may perhaps be the one that sets it back again. I for one, hope the game gets released in all due fairness to the fact that its film equivelents have little to no issues.
