Not many tbh. The Last Of Us and Red Dead Redemption series gets very close in terms of the level of violence.
This medium in general seems to stuck in this fisher price area where artist are scared to actually use this medium to express those ideas.
Shows, books , films etc have all captured those ideas better then games cause they actually dare to go that far and that raw. There is no excuse, we are also talking about a medium where some of these titles can go into hundreds of hours and actually capture those ideas THE BEST compared to other mediums.
So long as we keep calling it "gaming" and keep making sound like its lessor and should be treated with kid gloves, you'll see people look down on the medium and I can't even disagree with them. Who is really fucking suggesting someone play this game to get a good understanding of this event vs a book, film etc that ACTUALLY really fucking states what occurred?
So when we get an American History X, Cape Fear, The Grey Zone, Straw Dogs, Because Of The Cats.....Rashomon etc level of content in a "game" then we can get that proper telling of this event, until then....we'll continue to see this training wheels, fisher price type content where a game rated M, is acting as if its a Teen, PG 13 light hearted cartoon. The fact that the fucking game has a black and white mode named after a legendary director, yet fail to even make the game's theme even fit Rashomon despite wide spread rape happening during the Mongol invasion is hilariously tone deaf. The irony of being a game made in 2020 failing to even meet the dark theme of a fucking 1950's film....
This is where we are at with the medium and though we have progressed greatly with technology, we haven't moved that far in terms of subject matter.
