You get to live out your dreams of world domination, dictator and commander of men, however a series of rebellions by extremists will dethrone you a quarter of a century through your reign. You are left to your own devices, alone, in a nuclear bomb shelter, enough food and power to to last you the rest of your life. Through the walls there is no access to any forms of outside communication however.
Right then, my wish... probably a rather cliche and common one, but oh well. I wish I could possess a body that is attractive, and that I can finally be happy in.
