It wouldn't necessarily be THAT big. I would assume that all planets/solar systems/galaxies/universes are radomly generated. Basically all you'd need would be the parameters under which these things can be created. It would, of course, have a huge load time to start out with, or the these things could be generated as you gain the ability to visit each.
