Setting / Backdrop has come up in some recent discussions as well, regarding a game in design and situations. How much is too much or too little? I think that depends on your taste. A game like Symbaroum is heavy setting. Glorantha is heavy setting as well and it changes depending on the system you play it with. Shadowrun is tied to the Sixth World and Earthdawn is tied to the Fourth (I think).
As an aside, who doesn't miss the connection between Earthdawn and Shadowrun? Maybe it is just me).
But the Chaos Marches really can be played with any fantasy setting. It borrows art from BECMI D&D (Larry Elmore to be exact) and needs a once over. I may add a FAQ if people find it useful enough and ask questions, though the point is just to fire the imagination and create a space to explore. I might do a space version as well.
I do have a map of sorts, but am not posting that yet. I want to see if it is needed.
Here is a link.
