I was thinking of any and all options from 3, at the same time, I didn't want to try going for the "road warrior" look when it comes to the generics, as I wanted something recognizable. I was gonna do power armor, but realized, I just don't have the room for that. Granted, I am sure I can do just about anything from 3, as long as I have a pip-boy.
I did have a crazy idea of doing the "Gary" vault dweller. That vault where all of them are named Gary and say stuff like: "Gary, hahahaha!" I was so humored when I first went there and heard that. I can easily do that as well, if I can remember what that vault number was.
