Too many black people!?! White genocide!! Erasure of proud European history!! REEEEEEE!!!!!
...Seriously though, I don't really see a reason to cry over this. There were people of non-European descent involved in the war, at this point he (and the many other idiots on the net) are crying because the percentage of non-whites is wrong. ...Which among the lesser historical inaccuracies in the game and this "40% of British soldiers seem to be black" would only be true if the multiplayer classes were claimed to be an exact representation of the ethnicities in the army. Instead it could just be that the game focuses on specific units and people. Also, complaining because this is a game (one of very few) where you "have to" play a black person is just yet another example of how some people only realize how important representation is when they themselves suffer from it. I don't remember people complaining that they couldn't play a black transwoman in Battlefield 3 for example.
Gotta say, it wasn't as bad as I feared from the clickbait title.
I don't see much of a problem with diversifying WWI armies. The token black German exempted, it doesn't strain credulity for me (though tbf, I've never been a history buff). It may not be historically accurate, but it's hardly immersion-breaking.
I also disagree with his argument that DICE has an obligation to accurately portray the ethnic makeup of WWI armies. Were they using historical figures, I'd agree with him. Were they billing the game as historically accurate, I'd also agree with him. But AFAIK, all the playable characters were created for the game, and it makes no pretenses of being a documentary.
Not to mention how he contradicts himself. Right on the heels of his claim that it's an insult to the memory of those who fought and died, he says people shouldn't learn history from pop culture. So... which is it? Does DICE have a moral obligation towards accuracy, or should people be expected to find the truth for themselves?
