Well I've had 2 Nords so far, both females. In both cases, they were pretty much ruthless fighters (like you said). The main difference is my first one, Renee Gade, was sort of this jack-of-all-trades who did every quest thrown at her (or tried to). she also was quite immoral. If money was involved, she was all about it, regardless of whether she had to steal or assault somebody.
My newest Nord is Dyan phor a'Cauz the Paladin. She's also a bad ass fighter, though she's Lawful Good and has deeper morals. She only gets involved with a quest if there's some sort of greater purpose for good. She prays to the Nines, goes to chapel, etc. She's more of a noble Knight-type character who's good with a blade and only casts certain spells (which are based partially on D&D rules: Light, Sheild, Turn Undead, Command, Detect Life, and Dispel). She also is proficient with all the healing & cure type spells.
I like playing Nord characters. I'm surely gonna make a male Nord Barbarian one of these days...
Spartan is a great name for a class, btw. :thumbsup: I'm thinking my next Renee Gade character is gonna be based on the whole Sparta/Athens Greek warrior type. She'll wear only Arena armor, too, for battle clothes!
