Okay, starting a new character, hit me with your best shot as to what is the master race and why?

Well my favorite class is Nord for the fairly basic reasons: Gifted in combat, natural cold resistance makes for a pretty good warrior. But the next race I have the most fun with the Argonian race. They look very unique, they have a small upperhand with unarmed damage and can breath underwater. The have a poison resistance as well. There are also a few intresting pieces of dialogue while playing an Argonian.

Worst. Title. EVER. Seriously, "master race", don't you hear yourself?

Anyway Orcs and redguards are good warriors, Bretons & Altmer good sorcerers. Breton's 25% magic resist is really good. I won't spoon-feed this anymore than that, use the online resources:

BTW you could've found these by googling "Skyrim races", don't just start pointless threads please.

Yeah, it's unfortunate. But since it's already there...
Altmer are obviously the master race, The Pompous Altmer will surely tell you why

The Altmer or High Elfs are probably the master race, followed closely by the imperials, they have an empire after all.
