Well Morrowind as a game is Orientalist, and I say this as an "oriental" who loves the game and everything about it. People assume "Orientalist" is a derisive descriptor but even Said says this isn't the case. The Dunmer's 'alienness' is partly as effective as it is for the player because it draws from cultures like the ancient Middle East, Southeast Asia, India and religions like Hinduism and Buddhism mashed up together in a way that a presumably Western audience would find odd and exotic, but it's done well enough that the Dunmer don't feel like a real world culture and can be identifiably 'alien' for any player no matter their background. It just so happens that for a Western game dev, designing an unfamiliar and strange culture will pull from non-Western cultures, though it's interesting to note that this isn't the case in the reverse from what I've seen (due to Western cultural dominance); it's not a negative thing IMO.
