Agreed! Compared to many (most?) other RPG’s, Witcher is doing a decent job at keeping its armor and clothing design rooted in real history - where with most games it might be about 40-50 %, Witcher might be… say, 75? 80?
It’s not 100 and, well, surprise! It’s a fantasy setting!
There’s really no point arguing about how authentic the armor in Witcher 3 is, both the female and the male armor. Look just at the apparel that Geralt is wearing on most of the promo shots. The one you start with. That badass leather armor with layers of set-in chainmail.
It does feature medieval-authentic materials, but that’s really as far as the “medieval” goes here. Otherwise it looks just like a contemporary fancy take on a medieval armor. A modern-day spec-ops armor meets its medieval counterpart.
If you go and and take a look at more of the armors featured in the Witcher, it’s apparent that despite the above-average attempt to go authentic the designers in CDPR still also put a huge emphasis on fashionability and cool looks.
Personally, I’m not too thrilled about that, since Witchers (and Geralt in particular) were originally always depicted as relatively poor wandering swordsmen that just manage to make ends meet and dress practically rather than fashionably. In the games (and in W3 especially) Geralt keeps on being dressed more and more like royalty.
But of course, the pragmatic game design reasons are obvious. The game has to sell and to sell it has to attract even people who would not buy it normally. So we have to count modern day hipsters and dandies in too… I guess.
