All these are off the top of my head. There are probably a few I'm forgetting.
Fave Male Imperial: any generic guard, especially IC and road patrols. A couple of my PCs got a crush on Keld of the Isles, but I personally think he's dumb as a rock, and not as useful as a rock can be.
Fave Female Imperial:
I'll get back on this one...
Fave Male Nord: Ongar the World Weary.
I need a nap..hmmm Fave Female Nord: Agnette the Pickled is up there. I'd hang with her I think, if I had to live in Cyrodil. we'd party and get drunk together, and discuss goblins and mudcrabs.
Fave Male Orc: LORD RUGDUMP. OMG i wish I could have him over to my next dinner party. The guy who runs the bookstore in Leyawin would make a close 2nd place.
Buy a god-dam book! Fave Female Orc:: Mazoga. Of course. Yes Ma'am...uh..I mean Sir.
Fave Male Redguard: forget his name. The guy who shows up during KotN..hangs out at Luther Broad's. That's the one. He made me cry a little during a certain part of that quest.
Fave Female Redguard: Rasheda, I think. I forget. She runs the weapon shop in the Imperial City. I just like her for some reason.
Fave Male Breton: Hmm. Probably the Arch Mage. He just seems very kind, and
during the Mage's Guild questline.
Fave Female Breton: This is gonna sound weird but I LOVE Breton Conjurer and Necromancer women. They just sound so b!thcy and serious as they're attacking us. I can't think of a named NPC, though.
Fave Male dark elf: Umbacano, probably. He gives my PCs lots of tasks and money. I always look forward to seeing him.
Fave Female dark elf: oooh...that lady who runs the alchemist's shop in Skingrad, without a doubt.
Fave Male high elf: not a clue.
Fave Female high elf: can't think of any, atm.
Fave Male wood elf: the guy who runs the Archery shop in Bravil.
Because a perfect arrow flies for ever. I'm xxxxx. And I have no perfect arrows.
Fave Female wood elf: [censored] my memory svcks.
Fave Male & Female Argonaians: Don't have any. The concept of lizards that speak plain English bothers me. I'd rather they be like goblins: in their own element.
Sorry.
