Whether the responses were fake or otherwise, I have to agree in part with some of the sentiments raised.
Particularly that one line "You want to have fun... Killing people?" Sure, in Dead Space they're no longer people, but disgusting, nigh-on possessed, mutated shells of their former selves so killing them is less akin to murder and more akin to a mercy killing, but the fact that such gratuitous violence is generally viewed as such light entertainment worries me somewhat.
To me, it's like the difference between Saw and a David Lynch movie. Only Saw is Dead Space and David Lynch is Silent Hill 2. One is gratuitously violent with little context aside from AWWW SHIT NIGGA and the other is a reflection of deeply complex and fractured psychology, which makes any gore used far less exploitative feeling.
Eh, aside from that, Dead Space isn't even scary, I'll stick to Silent Hill to get my horror fix, cheers.
