Modular settings: a setting that is described in such a way that you don't need to read 50 pages to use it. Given that, is it possible to take any setting and break it into ever increasing lumps:
1. Introduction
No more than 6 paragraphs.
2. Lite Version
Enough to understand the setting and get excited, not so much it takes days to get through. 5 pages?
3. Core
The core setting but lacking in detail in certain areas. Quite deep.
4. Sourcebook (many of these)
Goes into detail about one particular area that the GM wants to run a particular campaign in.
Let's say we took a few games that have HUGE settings. Erm... Icar, The Artefact and Dead & Back. How would we make them lite game friendly? An few paragraphs of introduction isn't quite enough - perhaps a page isn't even enough. Would it be possible to turn those huge settings into a setting that would sit in front of something lite-awesome like Warrior Rogue and Mage (by Michael "Stargazer" Wolf)?
Would you have to cut huge amounts out so that it wasn't the setting anymore? I'm throwing that out there.
