I think the main issue is that nowadays it takes a LOT to shake us gamers. Doing it via ultraviolence pretty much went out the window once GTA 3 came out and let you run over innocent civilians with a tank. From what I saw in Total Biscuit's video, it looked like the game wasn't really TRYING to shock people, or if it was it didn't do a great job. The main character's dialogue is cringe-worthy bad, and the actual violence itself isn't particularly over the top or shocking. The most "shocking" violence I've seen in games came more from the realistic violence, such as in
TWD or
Heavy Rain. I view this game's violence and "controversy" like I did to the Modern Warfare 2 "No Russian" scene. I had no attachment to any of the characters that were being mowed down, so who cares?
Inevitably while I think the game will benefit some from the controversy surrounding it, I don't see this being a particularly big seller. PC Gamers are pretty smart and can see BS pretty quickly and I'm sure the negative reviews will come in enough to dissuade most people from getting the game.
One random note: I Don't know how much the game costs.
It actually has no price listing on Steam. Can't remember the last time I Saw that.
