Altmer.

They have an attribute bonus.
They run faster, jump higher, and hit harder because of their scale.

Race: Tied between Nord and Dark Elf ever since I first started playing TES with Morrowind. For Skyrim, a Nord of course.
six: Male, since playing as a female tends to feel odd after a while. Although looks really aren't that important to me as at least 90% of the time I'm in first person view.
Armour: I prefer heavy armour most of the time, and in Skyrim for a Nord probably Ebony for a knight look and ancient Nord for a more barbarian/berserker look.

race: redguard
armour: bothia ebony without helmet
weapon:daedric sword with paralyse enchanted

ps: am i the only one who thinks theres a huge lack of argonians in the game. the only ones i know are the bee and barb ones the ones outside windhelm the one at the shipwreck at dawnstar and the darkbrotherhood one

I prefer Imperials.

They can be pretty much anything in this game. Assassin, Mage, Warrior, or Thief you name it. Sometimes ill start out as an assassin type and then want to switch to a battle mage or something. And it doesn't seem out of place to do that. Where as lets say a nord, they pretty much fit the warrior stereotype and it would seems out of place to see a big muscled nord sneaking around stealing things or throwing magic.
