  I would definitely be out of my depth with handling all that! I think I would plan to find the right people that could tackle all of these points and give them leading roles in my colony.

  There are a lot of ‘ifs’ in this question! If we have a space colony, what sort of technology do we have to run the space colony? Would our colony just be a spaceship surviving on oxygen tanks and radiation shields, or do we have some sort of technology that generates supplies? Hopefully, we would have some sort of terraforming equipment (but better than the G.E.C.K. in the Fallout series!) to help us mould a planet to survive on.

  I think I would make the colony into a Kingdom that I could be in charge of. Currency depends on what resources we have on the planet, and what is actually valuable! Perhaps we could all play golf for pleasure – astronauts seem to have plenty of fun playing golf on the moon!
