Reasons for creating an artificial world:• Test theories about Biological
Behavior or Physical Properties• Fun and Games• Training and Rehabilitation

How To Create an Artificial World:
Observe real life and identify Variables…Discover what effects things. If you change something what is the result.
Develop rules to simulate this life.
