Ever since I invented the main protagonist of my story, every RPG I ever played I 'had to' play as him.
In Morrowind it was an Argonian, as it was coming closest to my little dragon in appearance and I couldn't do much to make it closer myself, yet.
In Oblivion I was immediately turned away from using an Argonian by Bethesda's cheap costumed-human approach they took this time around.
As I still had to play as Drake, I decided to go for his 'human' shape this time instead, and 'Breton' came closest in appearance.
Thus a sword-wielding young Breton it was for my first play-through in Oblivion... and for obvious reasons I leveled up this fire magic thing infinitely.
Later I learned how to fix the Argonians to my liking, and after I learned to create my own meshes, Drake's 'race', as a shape shifter, became a lot more 'indefinite' all of a sudden.
Apart from running around in full-dragon shape all the time, you can't scare those poor Cyrodilians with a big red winged fire-breathing lizard everytime you enter a city,

What 'race' that is? No idea. Probably something halfway from Breton to dragon (It was inofficial development stage #17, if I recall correctly, but I'm not going to count them all now).
But this is Drake, and this was the first "real" race I was playing the game as. Everything else was just 'testing' so far.
So yeah... still voting for 'Breton' though, due to a lack of modded races.
