Almost all of my characters have been Argonians in all TES games (since TES 2: Daggerfall). Argonians are very unique (difference is interesting), and also perfect for the kind of funny unlikely hero characters I love to play as. Just look at my Dragonborn character in my signature. Not what the Nords expected.
Same thing. When I try playing as a human character in a fantasy game like Skyrim it's just boring. And I have never liked elves.
