Well, I made my own stance oin this topic clear in the past...
But I think its so easy for devs to avoid any kind of fallout... Simply Don't. advertise. your. game. as. historical. when. it. isn't.
Will there still be outrage warriors? Of course. But they have a much thinner leg to stand on when the dev comes out and admits flat out that they just produced a random FPS Shooter with a light WW2 skin (or a fantasy RPG with a medieval skin) instead of calling it realistic and integrating BS "history tours" into their fantasy egyptian looking world.
On the other hand I had to chuckle hard about the other sides outrage warriors going ballistic over Kingdom Come. Hey, you know, right back at ya... don't like it? Don't buy it! The devs clearly wanted to stick to a realistic depiction of historical bohemia. And they didn't wanted to concentrate on that one black moor that might have found its way into bohemia at the time.... or the few jeanne d'arc stories that survived the times. From what I have heard and seen, it pretty much matches the history I got taught in school about medieveal europe... so call it all the -isms and -phobias you like, I my eyes the dev of that game stuck to history as taught here in europe. Maybe the history taught in school is wrong, yeah. Still historical accurate from what we know about medival bohemia today.
Do I think it was the right thing to do? Well, it seems to have financially turned out to be a good idea. All the outrage warriors running amok against it probably should create their own historical RPGs set in bohemia if they don't like it... I am sure they would trigger a lot of the historical accuray outrage warriors as a bonus point.
Now, trying to see it from the lens of someone with a different opinion on history... yeah, maybe they could have gone easy on the historical accuray stuff. But then, without that their game probably was just another RPG, decent maybe, but not that earth-shattering as I heard, and who could resist the free marketing of a million outrage warriors selling the game to the ani-SJW crowd... so again, probably shouldn't have ridden the historical accuray train like CoD WW2 shouldn't have. In the end, even history has become subjective nowadays.
So really, devs not dealing with a) a long running franchise and b) not trying to sell their game as historically accurate, should do whatever the hell they want. they will get attacked by outrage warriors anyway about something silly. Putting "historically accurate" on your product will just paint an even bigger mark on your products forehead.... so unless you want free marketing to cater to a specific side, you probably should just keep your marketing shills in check.
