I like Argonians because Lizardmen, but I think my favorite is Redguard. While I love the look of the Argonians, the Redguard also have the benefit of some awesome looking armor, interesting culture, and an awesome desert homeland. Once more lore comes out for Argonians, though, that may quickly change my mind : )
Khajiit is my favorite race, just because nothing is more badass than a humanoid cat carrying a steel battleaxe on his back. And their lore really got me, as well as their accent...
But I also like nords for #ThatVikingFeeling. I also like dunmer, but I was never able to create a really good character/build to make justice to their awesomeness.
My favorite race is Argonian. It was the first race I chose in elder scrolls, I think lizards and dragons are cool, and since my first character they've always just stuck on me. Their lore is so intriguing and holds a certain air of mystery that makes ya want to learn more about them. Also Histskin is made of win.
I also really like the human races, mainly Nord and Breton. It's easy to get immersed if you play as a human, especially if you model them to look as yourself. And of the Elves I really like Dunmer, Orismer and the Snow Elves (I hope they become playable, but I doubt Beth would make them playable)
but yeah, Argonians all the way!
My favorite race are the Imperials,
I love how they are, their organization, his speech abilities and trade, how they can be a"Templar Knight" or a Corrupted politician, I like the way they are proud to be an Imperial, they are good soldiers too and have strategic abilities on battle (supposedly), and they always have resources what its very cool, for me they are like the middle age European and I like that a lot.
I like the Imperial City a lot, I enjoyed playing Oblivion, the castles, towns and every thing looks there so medieval, love it
My second race are the Nords, like about them the survival way they are, their strongest and their brute way they can be, the companions is a nice guild, like his lore and the werewolf part of the guild its really cool, I like the way how they have to fight to get his reputation in some way
And my Third one are the Dunmers, love their culture, the place where they lives and his constructions are so cool, they have a very rich story, the guilds and houses, their gods and religion, their are so mystic, are like from other world, I look them like the Asian middle age and that's interesting
