While digging through a multitude of bookmarks, to see what I could dislodge from the browser, I found two that I had forgotten about and would like to share:
Dawn of Worlds: a minimalistic world creation game that allows you and your gaming group to build a full fledged setting from ground up. Roll some dice, spend the points on anything from terrain creation to cultural explosion and wars. When the evenings over, you should have a map, time-line, and a lot of fun!
The Mule Abides: 9 Minute Campaign Design. An old post from Nov 2009 that asks questions to assist in describing your campaign setting in '9' minutes...
Nope, I can't do it either. But interesting none-the-less.
