on another note...I think beth hates khajit. I mean barely any khajit npcs,none that can be married,no unarmed skill tree,didnt get the facial vampire upgrade,some glitches in dawnguard that turn khajit into an imperial with a cat face. I honestly dont think beth will be doing anything with them in skyrims future.
Alternatively, it just doesn't make sense for there to be that many Khajiit in a cold climate, where they're generally treated with suspicion and can't live within city walls. I think the marriage thing was an oversight (maybe because they don't have homes? Or am I talking rubbish here? Don't marriage partners always have their own places?)
My first character is always a khajiit, so I do feel the pain here...
