One of the things I noticed, and like, about the Redguards was that their culture isn't just a single copy-paste of one earth culture, rather it mixes elements of high north africa/araby with swashbuckling europe and traditional african religion/voodoo. I've wondered why they don't do this sort of mash-up with the other human cultures of Tamriel, blending these elements into something different but strangely familiar.
I was kind of dissappointed that they just copy-pasted norse mythology and vikings and then slapped different names on everything. Sure the Forsworn are different, but you don't really get to see that much of them. They're also a seperate culture from the Nords - If the Nord culture had been changed to add in many elements of Forsworn culture/aesthetic and perhaps some real-world Russian culture, they could have had something original.
Really? Try playing as one of the Elf races - you'll find plenty of racist comments & behaviour!
After having played Dragon Age, I find it a very refreshing change to see Elves as the oppressors. The racism towards your high/wood elf character in Skyrim is tempered with fear - the very real inquisition that will steal into your home at night and drag you off to be tortured if they suspect you of worshipping a false god.
