I think this particular topic of videogames is not considered fairly. Videogames get a lot of shit because of two reasons:
1.- Interactivity.
2.- Constant striving for realism.
People role play, and immerse themselves in a series of rules where they can go around committing fictional crimes or acts of violence. Again, the problem is more akin to the idea of violence and its perceived acceptance by specific sectors of society according to a big portion of traditionally inclined people.
Time will come when the actual censorship will have to be done "in house" rather than from the outside. Developers won't want to be associated with a product that could be argued to promote actual violent tendencies or delve into distasteful territory when dealing with the realism of the works they will be producing.
The fact is, that within fifteen years, technology will have gone so far as to render a person's innards coming out after a particularly powerful blow in extremely realistic fashion and by then it will be considered normal in games of that ilk. Also, videogames are far, far from neutral when it comes to violence. The idea of violent confrontation is very much part of us, but used "as is" as direct means of addressing conflict is very seldom used in entertainment. People proceeded to shit tons of bricks over manhunt 2 no matter the game looked silly and didn't have the best graphics, what bothered people and the conservative pundits was the idea of murder simulating for the fun of it because, make no mistake, many videogames are indeed murder simulators when looked at from a pragmatic lens albeit bad ones for now, though one could argue that that's the case for consumer avalable goods; the U.S military is already using VR simulations for actual soldier training so there you have it, maybe it doesn't look pretty but someone up there in the army thinks it's useful.
The sole act of saying "lay off my games!" doesn't solve the issue in my oppinion. Games have to be scrutinized a lot, and even more now, with the coming technology being projected as far, far supperior than our current one. Just shoving the issue aside doesn't do anything in favor of the gaming community.
I was going to delve into matters about sensitivity to violence and whatnot but decided to stop at that.
