Well i actually have 3 (because im an indecisive sod)
Nord: simply because i wanted to play the skyrim from a 'locals' perspective but turns out that frost resist is bloody useful and in close combat they're pretty good hence why they turned into a favourite.
Khajjit: Like you said; Stealthy, deadly and a cool idea to put in a game
Argonian: same as above, plus poison and disease resistance helps a tonne
Nord: Vikings!!!! ?
Khajiit: It's fun to sneak around and slit the guard's throats.
Argonians! : They are lizards, why else?
hmmm looks like khajjit is winning at 7 votes
Khajjit and nord is drawing at 7 votes
stealthy and deadly.
