It was Reno. And I think this post shows why it was the best RPG area of all time.The Youth Counselor said:I remember in Fallout 2 I ruined a family in Nevada during my first playthrough. (I can't remember if the city was Vegas or Reno.)
The mother and daughter were both prostitutes, and both had addictions. I killed the father/husband of the family, drove the daughter to get hooked on drugs and got them both pregnant.
