Well, here's my view. I've played BF1 but that's my only Battlefield game. I'm not a big gamer anymore and never play outside of winter, got other things to do.
I am not an expert in World War 1. But I bought BF1 because I liked the trailer. It seemed pretty darn realistic, certainly about as realistic as it's possible for a video game to get. It starts with you playing soldiers who get killed again and again, relentlessly. The starting sequence of BF1 really impacted me, it makes you realise the scale of the slaughter and hopelessness of the fighting. in ways a po-faced documentary cannot. No matter what you do, you die within seconds ... and then the camera moves to another soldier. You play that soldier, you die within seconds regardless of what tactics you try. There is no way to survive. They made their point very well.
The rest of the story mode was equally well done, the multiplayer was fun. The graphics were great! The locations of real battles were used, the weapons looked convincing, the soldiers looked convincing ... oh, wait. Except for the black men in Germany's army?? Since when did World War 1 Germany have an army filled with black dudes? Since never? This is the country that just 20 years after World War 1 was fighting a war of white supremacy. Also one day the game updated and suddenly the startup picture was of a female soldier.
I admit, it did bother me. I put it to one side and continued to enjoy the game, but it bothered me for all the great reasons explained elsewhere on this thread - because I know the game developers tried hard to be realistic in other areas and deviated in these specific areas because they believe shitting on men like me is virtuous. It's not some holy commitment to realism that caused me to be bothered. It's because I know the aggressive and unpleasant tactics that would have been used to create this unrealism, because I know why DICE did it.
I resent it because I know that they were trying to subtly rewrite history as they genuinely believe that if I see a woman holding a gun when I start my game at night, tomorrow I'll go give a job or a pay rise to the women in my team ... not those awful 'privileged' white men. I resent how delusional this belief is, and how they think they can influence me by lying to me about what WW1 was like. I dislike where this is going because all totalitarian societies in history have been characterised by ideologies of racial hatred, rewriting of history and massive lying in attempts to manipulate the population.
And ultimately, when I saw the adverts for BF5, I thought about whether to buy it or not. Again, I'm not a serious gamer. If I had bought it I'd probably have played it for maybe 10-15 hours tops in the next 12 months. If I'd been in love with BF1 I might have made an impulse buy, Xbox Live certainly makes it easy, but I quickly Googled BF5 and saw people complaining about the even more amped up SJWism and all that it implies. So I decided to pass .... the slight temptation to play a game with nice graphics and music was outweighed by the apathy I felt at financially supporting people who hate me for no reason. I bought Red Dead Redemption instead although so far I don't think I've made it through the tutorial, I'm still stuck on some snowy mountain.
People like me are sort of like the dark matter of the video gaming universe. We don't make or comment on Youtube videos, we don't play intensely, we suck at multiplayer and on the few times we try it we always come last in the league tables with 15 deaths and 1 kill if we're very lucky. But we pay the same for our copy as everyone else. It doesn't take much to sway us from one title to another. Maybe that's part of why BF5 didn't sell well.
