… but this one just gives such great answers.
I will conquer: The Moon. Beat that. (Where I will build The Alan Parsons Project.)
My title will be: Bill Gates. (I think I might enjoy the position more than the current holder.)
I will succeed by: Brute military force (Robot Hunter Killers.) (“using wave after wave of my own men…”)
My Enforcers will be: LV-426 Aliens. (I’m fine as long as no one sends Predators or Sigourney Weaver after me.)
My first act as ruler: Make smoking a capital crime. (… I’m just leaving that one where it is.)
