The attitude is undoubtedly problematic, and everyone should be able to see that. Should the game not be made, then? I think the game has every reason to exist (screw rights, they are unrelated here) if it comments meaningfully or helpfully on the theme. Does simply simulating the murders and making entertainment or an aesthetic (no matter how base) experience out of them constitute a comment? Perhaps, but on what? That we are like this? I can see some value in that, but I also think that the possibly deleterious effects of such unadulterated violence would be avoided very easily through this comment being made in an Onion article. Satire, then, would be the path I'd advocate. This is not satire. It is analogue, a reproduction, and as such does not count as being critical or witty.
I think this game IS satire of a sort. It's taking the idea of unrestrained video game violence to such an extreme and over the top level that it can't do anything BUT be satire. The lack of plot, the victims that do nothing other than scream, and the only drive being 'pure hatred', puts a spotlight on the ridiculousness of computer violence.
You (and others) seem to be thinking very deeply about this, but it comes across as though you (and others) don't think that the creators of the game could have thought as deeply into it or made the game as a mirror to our obsession with violence.
It's like Landover Baptist Church (
http://www.landoverbaptist.org/), whilst they've become a bit more jokey recently, they started off with a lot of articles which were just a
tinyshade more fundamentalist than most fundamentalist churches, and that starkly highlighted the ridiculousness of that sort of fundamentalism. As with this, a lot of people thought they were playing it straight and really thought that - and they never stated otherwise - as that would suck all the power from it.
Granted, they could be actually playing it straight and just have a really terrible idea for a game, but it seems unlikely.
