How so? While fantastical settings and material culture can work if done properly (like Morrowind's Dark Elves), most of the time the more "fantastical" elements in arms, armor and architecture are just really badly made medieval European derivatives that look worse than the real thing.
Take Skyrim for example. Most of the armor and material culture in Skyrim is absurdly poor, majority of their armor is functionally useless while also being ugly, their clothing is ill fitted for the climate, and their architecture is passing at best. Compare that to Vendel era Germanic peoples or earlier and you have a much brighter, more beautiful and more intricate material culture. Hell, you could have swapped the Foreswarn out with La Tene era Celtic peoples and ended up with a far more interesting faction than "generic stone age fantasy barbarian 101".
"Battle Brothers" is probably one of the best examples of more realistic arms and armor done in a fantastical setting, despite not being an RPG and kicks the shit out of other settings. Its grounded and believable, and the world sucks you in, in a way that most RPGs fail to do.
