the all point for me is:
was it really necessary to make a russian faces dlcs?? aren't the russians the same Europeans as Poles, Croats, French etc?
I understand Mongols and Blacks dlcs but not the Russians one. For me it should have been limited on changing the clothes to more 'russian' ones and stop.
Tricky question really.
Russians do differ facially from other Europeans, just like Italians differ from Norwegians, and just like Nigerians differ facially from Somalians, both are still Africans, but they look different.
I am English, and whenever I meet Russians, I can say that I do notice different looks about them, they are still Europeans so these differences are subtle obviously, but I don't feel I look as similar to them as I do with other Britons or Irish people around me.
So the question of whether it was needed? Perhaps not, they are, as you say, Europeans, in fact the Rurikovichs were descended from a Swede, but at the same time, you could argue a Republic/Italian faces DLC isn't needed because they are also European, they still don't look the same as a Briton or a Dane for example.
I've said it before, but I actually think the Russian faces are better than the vanilla European faces because they look more rough and realistic, compared to the more plastic faces of vanilla.
