Akatosh and Alduin are two separate choices, yet no Lorkhan?
From what's been listed:
Hammerfell - I liked Stros M'Kai, and most areas in Daggerfall's portion of Hammerfell were pretty okay too for what they were. Plus, Redguards are my favorite race, their pantheon is awesome, and I want to go there.
Lich - Undead mortals who still retain their mentality but become total hardcoe badass skeleton spellcasters and are cooler than vampires will ever be. Hell yeah. (Dremora are cool too.)
Vivec - Lorkhan would have taken this one, but since he wasn't included...it goes to the magic hermaphrodite, the warrior-poet, Vivec.
Clavicus Vile - Such a hard choice to pick a favorite Daedric Prince. Most of them are great. Honorable mention for Molag Bal, Mehrunes Dagon, and Hermaeus Mora.
Dagoth Ur - I don't really like the category of "evil guy" but hey, whatever. Dagoth Ur is the most interesting. Mathieu Bellamont is a disgrace to the other names on that list.
Nocturnal. I don't think this one has to be defined. Since I am a huge thief(in Oblivion) She is my favorite Daedra princess
It would still be Daedric Prince, since they have no real gender and can take on whatever form they want. Also, if you ask me, Nocturnal is a disgrace. I haven't seen her steal a damn thing, yet she always gets things stolen from her. The cowl, the cloak, the Eye of Nocturnal. A few games from now, she won't even exist, someone will have stolen her place in the list of Daedric Princes.
