From publisher blurb:
Role-playing games are great – let’s learn some!
Hand these guides to the new players at your convention game, use them to convince your friends to try a new system, or read them yourself to learn a new game.
These explanations aim to help the reader grok the basic mechanical concepts these systems use, to allow them to understand how the system works. For accurate details and further rules, read the rulebooks!
Useful for Fate Core and probably also Fate Accelerated. We weren’t paid to create this, we just like the game.
