One of the most important tools that I use is the map. Having a map allows me to do many things that are extremely beneficial in both the writing of fiction and for running tabletop games. Some of these include army logistics, travel times, and population control, all of which I find extremely useful and at times, indispensable.
To be a god. We’ve all wanted to do try our hand at omnipotence one time or the other. To have that absolute power at our fingertips, to be able to say who lives and who die, to watch the rise and fall of nations in heartbeats. What better way to fulfil that megalomaniacal (is that a word?) urge than to build a world?
