Well i made a Nord for my big RP playthrough because he's a true son of Skyrim. Then i made a woodelf theif for the thieves guild. I also made a Khajiit assassin from the Elswjer(spelling?) dark brotherhood, who joins the Skyrim one. Finally, i made myself. I suddenyl found my way here, and was given magic powrrs lol. Really, i just wanted to make a mage and was too lazy to make a backstory, so i made myself. I accidnetly deleted my mage/self playthrough though....which was a bummer. I had like 15 hours on that dude.
I have actually done every race multiple times. But the ones I pick the most are Argonian and Redguard. I like the redguard lore, starting skills, an look. I like Argonian starting skills AND abilities. Also when I shout for some reason I feel like a dragon. Dark elf and bretons are awesome also.
