Judging by your avatar and username I would have expected you to use Dominate spells more than anything.

LOL I should do that! Max out my illusion skill, then make some dominate spells at the maximum settings. Then cast these Geass spells on every NPC in Cyrodiil, Elsweyr (Yes, I've got Elsweyr: The Deserts of Anequina installed), and the Shivering Isles! XD
Now, if there were mods to add Pizza Hut and Knightmare Frames...
Oh, I also chose intelligence and willpower as my favored attributes, while using Korana's http://www.tesnexus.com/downloads/file.php?id=30304 mod. Thanks to that mod, I can never go back to using the vanilla races. Use the Tribal variant to get the alchemy and marksman bonuses of a Bosmer combined with the magicka bonus of an Altmer. I intentionally bork my personality until I do Namira's shrine quest, since you can get by with low personality anyway (Cheap, overpowered charm spells render speechcraft moot), and overcome the low starting health by letting weak enemies pound on me while wearing heavy armor. Nothing like doing some min-maxing instead of playing normally. (It also helps that I'm running Francesco's overhaul--no more crap with the leveling system actively wanting you dead!)
Companions? I never use them. Other people just get in the way. And they talk, talk, talk.
