creating a world is easy but creating the foundation is the hard part. I was at that time making the first world itself, I learned that the world is a pocket of split space using the surroundings as energy to keep it open. I had to add small flaws if it was too perfect, and reverse if it was too unstable. the bigger the world the more it takes a toll on the multiverse and the area it has been placed at. to me it was a college topic to study, but for others it is getting a eight year degree.
