In this Citizen Academy video, you will learn about the exciting world of Instances, Servers, Physics Grids, and Zones! This is a rather complex topic, but CA found a way to make it fun and educational as well. He discusses how an Instance works, the function of the Galaxy Server, and the Generic Instance Manager. Best of all, this is presented in very simple to understand language! Then he provides a real world example of how all this fits together. Finally, CA explains the concept of Physics Grids and Zones, and then discuss Levels of Detail (LOD) for space ships.
