Sometimes, tho rarely as a "serious" idea. More along the lines of "Supreme immortal eternal god-ruler of the universe" or like some sort of Daedric prince that's got my own little world to toy around with, and having this world as some sort of pet project on the side (As in letting people go about their lives and businesses as before, but watching and stepping in where necessary to keep humanity from doing really stoopid things)
Realistically, I can't really see myself in any position of power higher than "Man of the house" or something similar xP
If you could make one species of Pokémon real, which one would you pick?
