I usually go for Redguard because I find the Adrenalin Rush ability very helpful in the beginning. My preferred star sign would be Atronach because I don't use magic that much. It has one major downside though and that is it leaves your character unable to restore magic points when resting.

Argonian, of course. Because that was what I have always made my main character. I always play as others afterwards, but Argonians rule supreme. Hail Argonia, hail the Hist!
