Publisher's description:
EN Publishing Mini-Games are a new line of products that use the existing System Reference Documents and other Open Gaming Content to provide tightly-focused games for specific genres, play styles and settings. They feature new rules like basic or advanced classes, new feats and skills, new races and even new combat or magic systems to generate a unique feel for each game.
Mini-Games are designed to be quick and easy to learn, based on rules you're already familiar with. They are ideal for a one-off game, a short campaign or for something to play when you want a change but don't wish to learn an entire new RPG system.
