Why the focus on geography?
Setting maps (e.g. regional, city, world, etc.) are important. They let you know where you are, where various features and landmarks are, and - most importantly - how these things spatially relate to each other.

Time is important, and the equation [geography + means of transport + external environmental factors] tells you how much in-setting time it takes to get from point A to point B.

Geography is also sometimes vitally important in the day-to-day adventuring lives of the PC, in that a PC's exact location on the map can be the difference between life and death when the fireball goes off or the cave-in trap gets triggered.
So time and space as a focus of play is one answer?I have never been particularly keen on concentrating on time and space in my RPG play.
What does that focus bring to RPGing?
