Not really. The give each nation/setting of each major game its own character by giving it different demographics. It's also an effort to preserve the canon lore of the game. Every area has its history and background determining who lives there. Catwashing (like whitewashing) a nation far away from Elsweyr with a completely different climate and a history of little immigration compared to, say, Cyrodil wouldn't make any sense. I actually applaud them for doing this, and that's not just because I am a fierce activist against recognizing Khajit as an intelligent race. All they ever do is steal.
Looking back, I loved the feeling in Morrowind where you were in a very alien feeling land where most of the Dunmer were quite hostile. It gave the land a lot of character. Cyrodil, on the other hand, felt much more universally accepting and friendly because it has a much more diverse culture mix and Imperial architecture is much more familiar to what we know in the real human world.
pro9b17 posted... Well, how many approximately? Three or four in the entire game? Are there cities that have lots of Khajit and Wood Elves, etc?
There are a few wandering Kajit, wood elves are sprawled around and some are enemy hunters that will attack you in the forests. There aren't whole cities, no. But if I recall they really don't come from this region and most migrated and are facing oppression from the racist nords.
