House Rules

The core z20 rules do not cover all situations. Instead, as the GM Toolbox: Things to Remember states, GMs are expected to apply a ruling (usually a ±2 or ±4 modifer is sufficient) to those situations they feel don't quite fit the norm. The following document is a collection of such rules accumulated through play, as well as a few various other minor rules tweaks and options.

This document is not meant to be canoical, but simply an example of the sort of house rule document you may want to compile over time as a GM in order to remain consistent in your rulings. (Still, it's OGL, so take what you like.)
