AWRPG is also supported by Supplement Books to add to the detail of the game and to help create new Genre Books.

These Supplement Books will concentrate on modifying or adding to the core system, not the Genre Books. They will include not only lists but design systems and new ideas for uses. All Supplement Books will be a trove of information and ideas to aid not just the GMs but the players of AWRPG. Nothing in these books will be “For Your Eyes Only” information, unlike the Genre Books.

Current Supplements being worked on are for Magic, Vehicles, Faith, Psionics, and a Bestiary of common critters. Rules for these Supplements are like those of the Core Rules; logical, simple to use and understand, and simple to modify.
