From the introduction:
The purpose of the Generic Add-On Booklet is to introduce gamers to the idea of generic RPG Add-Ons and demonstrate how Add-Ons from the Atomik Vortex Studio may be integrated into any game system. The rules of the game still come from whichever RPG system you are using in your campaign be that D20®, Fuzion®, Palladium®, GURPS®, FUDGE, Traveler, Cyberpunk, or your own home-brew system (all trademarks are the property of their respective owners). This booklet will show how the Atomik Add-Ons are design to be interoperable with your game system of choice without the need for conversion rules or system porting. You will find that you can use any of the Atomik Add-Ons such as Atomik Psioniks or Atomik Magick just as easily with an epic fantasy campaign as with a down and dirty "Old West" adventure.
