Dream of the Dragon

Dream of the Dragon is a rules-lite RPG-making RPG. It's easy to play, needing only 3 dice: d20, d6, and d4. Out of the box, it comes with the typical classes and races you'd expect of a fantasy RPG, but it also has rules for changing all of these and making new ones. That's because, to use a computer game analogy, the game is based on an engine, included in the rules, which makes it moddable. The rule book has everything you need to get going, including a sample setting and adventure. Dream!
