I want to PLAY ALL THE BUILDS and am slowly working my way through a list of characters I've planned out, after two "I don't know what the heck I'm doing or what class I'm supposed to be" playthroughs. Currently I'm playing:
Rowan: A Bosmer archer with a side of magic. She uses only a bow for offense, and wears robes which she augments with Alteration armor spells and perks. Arch-Mage of the College of Winterhold. Good at heart, she only kills when she must, never steals, and helps others as much as possible. Playing into Bosmer lore, she's also a strict carnivore, and cannibalizes her slain foes.
Gallifrey: A Dunmer mage who strictly uses fire-based Destruction spells and Flame Atronachs in battle; eventually he'll be conjuring Dremora as well. He also wears robes and uses Alteration armor spells and perks. Working his way up the ranks of the Dark Brotherhood. Evil as can be, he causes mayhem at every opportunity, and enjoys killing. I imagine him as a Mythic Dawn cultist, worshipping and championing the Daedric Princes, and collecting their artifacts. I'm also considering making him a vampire, but if I do it won't be until much later in his game.
And characters in reserve:
Annika: A Nord warrior who wields greatswords, wears heavy armor, and dabbles in Restoration magic. Her loyalty lies with Ulfric Stormcloak; she returned to Skyrim for the sole purpose of joining the rebellion. (I have a pretty detailed backstory for her.)
Marius: An Imperial warrior who wields a sword and shield, plus a bow for ranged battle, and wears light armor. Fights for the Imperial Legion. Being of noble heritage, he has no crafting skills and refuses to learn trades that are "beneath" him; he'll only be able to use gear and potions he buys, finds, or is given.
Khayman: A Khajiit thief who dual-wields daggers and uses a bow for ranged attacks. Wears Thieves Guild armor only. Will bring the Thieves Guild back to its former glory, and then some. Because nobody in Skyrim trusts a Khajiit, merchants (aside from Tonillia) will refuse to deal with him; he can only use gear and potions he crafts, steals, or is given.
