Regardless of what the developers support, and I'm not condoning it in any way, shape or form, this game, as disgusting as it is to some people, still has the right to exist.
This is a freedom of speech matter, plain and simple. You have the right to be upset, complain, call for the government to ban it, and that's your right, and this game has the right to be made, and really, is anything you see in this game as bad as the things you can do right now in games like Manhunt and GTA? This is a PC game, far removed from the realms of console gaming, free from restriction by ratings and a veritable Wild West of indie development, filled with Japanese Guro games, flash games like The Torture Game, RPGmaker horror games, mods that might not necessarily be your cup of tea, and many more things that you'd never see on consoles, and this game won't be touching consoles anyway. There are games that are far far worse than Hatred, and they've gone unnoticed because they are PC games. This would have done the same, but all the media attention has made this into Manhunt 2.0.
I likely won't support this, especially not if the developers are supporting what they're suspected of, but I support the right to create anything, free of censorship.
