All of the races from the previous Elder Scrolls games are back in Skyrim, although they've thankfully been tweaked to balance them out better. Now more than ever before, it doesn't matter what race you play. They all have their perks, and none have any crippling negative aspects so damning that the race is all but useless.
That said, all the races are not equal, some are better than others in terms of objective gameplay. Again, this character creation section is devoted to power-gaming, so the races will be ultimately be judged on their gameplay merits.
