If you ask me (and you didn't,) while we're getting off topic now, I would wager that the Khajiit are more likely based on the Katta from the Quest for Glory series. They feature very prominently in Quest For Glory III (released 1992) and then TES: Arena comes out in 1994.
Or it could be that people just like playing cats. I dunno. Does it mean we shouldn't be using enkidukai? No, clearly not.
Also, to call Nolthrir Argonians is a real stretch. Nolthrir are a race of elves, and Argonians are practically reptilian.
