@ltdaleadergt,
I think everthing would be simplified. There would be just a few kinds of metal, just a few kinds of stone, people would be like gigant intelligent bacteria calmly waging war against different gigant intelligent bacteria for dominance, etc.
Or maybe I would make the world exactly how it is, except I would ever so often do something immensely strange, such as making a gigant shoe aparear and fall and crush an important city, just to see the world's reaction.
