Skyrim isn't more 'realistic' than oblivion or morrowind. The only thing indicative of that is better graphics. Morrowind might have mushroom towers, fancy robes, and crazy bonemould pauldrons, but they had a logic to them. They're consistent with the world. You don't know much about the finer workings of mushroom towers, but you can suspend your disbelief because A: You don't know the material's properties and B: They were made by wizards anyway. Skyrim inverts that, yeah, it's closer to reality that buildings X and Y are made of stone, but X would fall appart if it was normal stone and built that way, and Y should be in a better state of repair if it's in use. There's a key difference here, and it's there for a lot of things: weapons, armour, clothes. Morrowind designs are more fantastical, but skyrim designs are more often less likely to work. It's skyrim that has the revealing leather, the studded leather, the too-fat swords, the metal bows, and the helmets that are smaller than your head(and the flexible metal armours, but that's a graphical thing) Morrowind and oblivion has it's share (the mauls for hammers)but the offender is skyrim, with it's more 'realistic' rendering.
also TES does deal with rape and genocide. Everything Molag Baal does for one, The falmer (dwemer?) and Ayleids for another.
Other than these areas where I have suggested you are wrong, I agree with you.
