Hey Adam, have you seen the similar charts in the 4e DMG2, Pathfinder Gamemastery Guide, and the WHFRP 3e GM book? They make some assumptions about system expectations on the GM as author, but I find the addition of the icon pictures in the example flowcharts (locations or NPCs or monsters primarily) adds even more 'oomph' to their visual appeal.
I have all three of those books but haven't had a chance to take a look at them in this light. I totally will.
I agree, flowcharts. I will talk to Sage about including them in places they might help!
