I am a gamer and I've never heard of such a game. Do you have any sources for this? I'm curious. It's not a mainstream project.
By the way, people didn't "sweep" the videogame violence thing "under the rug", it's just laughable and a classic go-to topic for old ladies who have no idea of how human psychology works. Suspension of disbelief is a part of every mentally healthy individual's psyche and if a videogame can influence you to kill people, then you are already damaged to the point that something WILL influence you to kill people one way or the other.
