Role Playing Rules Conversions

I’ve always loved doing role playing mash ups – as you probably know if you’ve seen my series Crossing Over – and I know that I’m not alone in this. But as fun as it is to just mash genres and settings, sometimes you need to switch things from one role playing system to another. And that’s always so much easier if the work’s already been done for you. And if the name of the system you’re using appears in the list below, it might just have been:

These conversions are grouped by inter-convertability – all games in a particular group are, in theory, convertable one to another, although the more systems a conversion has to pass through, the more distorted the results are likely to be. And of course, the level of detail and completeness varies widely.
