That’s been true for longer than videogames were a thing; Fantasia comes to mind, where Disney removed racial stereotypes from it (they did keep the topless fauns though…), because times changed and people found it extremely offensive. They still have an enforced warning in front of it, as do many of the older WB cartoons; they too engaged in Blackface and racial stereotypes, so it’s not like Disney or WB are trying to erase their racist past either; they’ve outright admitted it was not, and never was, acceptable, but edited it to make it more palatable while still being true to the original.
And I’m fairly sure the original of that sort of thing can be found on the Internet Archive.
There is a balance between making it acceptable for modern audiences and not desecrating the past here, and I feel like going so hard in one direction is just not that helpful. I don’t think people are going to forget the past because it’s not in the game (if nothing else, I’ll make sure they won’t). It’s the same excuse I heard people on Twitter say when 2016 and 2 were delisted. Like…no…2016 and 2 are still possible to download if you already had it, and even if you don’t, the games are well-documented by nerds like myself on both TV Tropes, Fandom Wiki and Wikipedia. It being removed from sale does not mean it is lost to time, that is such a jump to conclusions.
Hell, we can archive H3 ourselves and remake it; Steam has repositories for older versions of all their games, after all, so it’ll never be truly gone. I still have a partial copy of the CTT on my computer.
To use a Hitman example, @AnthonyFuller ported TS6 from the PS4 version of 2016, despite being removed content due to licensing issues. That got ported over eight months later, and I am certain IO saw this mod and decided to kick things into gear officially, either out of embarrassment or due to realising that it might be beneficial to do so. They saved their content.
This is a complicated subject that doesn’t have an adequately clean answer, for either side I might add. I know that this is not going to be a satisfying answer to everyone here, but it’s worth mentioning the complexities of the debate here. Reality is messy, and more often than you might think, it clashes with fiction.
