I play NV with my Fallout 3 characters, so:
Justine Hunter
Troy Hunter
but also
Augustus
for my special character, http://newvegasnexus.com/imageshare/images/1079527-1296930953.jpg
He is the deepest character I've had in any Fallout game.
I find myself thinking every decision based on the "unknown redeemer with shady past saves town and rides into sunset" image I have for him. He is early in the game but I know one thing: He is going to turn down Mr. House. Serving computers isolated in their ivory towers for centuries has not served Augustus well.
