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.
whatever race has the best stats and abilities/powers to whatever type of class im going to be playing. however, my main in oblivion is a khajiit i believe, and my main in skyrim is a nord.
