If that's true it's sad. Many of the ideas in Fallout 3 were borrowed from the elder scrolls. People even called it "Oblivion with guns". Personally, I loved that Bethesda was making Fallout 3, because I knew they'd take everything they learned from Oblivion and build on it, and they did. It's a shame if they decided not to do learn from Fallout like Fallout learned from Oblivion.
Honestly though, I know this doesn't bother you and that's perfectly fine, but do you see why it's sort of aggrivating to us? Especially when NPCs are talking about your race directly to you and don't even acknowledge it? For khajiit the very least I expected was a guard to give you the business before letting you into the city, but they just totally ignored you.
