I completed a Let's Play of New Vegas some time ago. I played as a complete SOB. Very nasty character.
If you want to have a look, please feel free.

If you don't want any spoilers, obviously do not watch any of the videos.

I'll have to take a look at that after I play as my usual goody goody.

Thank you (potential future) watching. :)

I could never play all the way a good character. Easily annoyed with assholes.
