Fantasy Flight Games has put their Fireborn RPG system up for download online (from a couple different game-download websites).
From the announcement:
Fireborn is a unique roleplaying game campaign setting from Fantasy Flight Games available for download through rpgnow.com and drivethrurpg.com. The GameMaster’s Handbook and the Player’s Handbook provide everything you need to create adventures and campaigns for this modern and mysterious setting, and The Fire Within provides players and GMs with an introductory adventure. In Fireborn, players take on the roles of powerful scions, human beings with the souls of immortal dragons, as magic begins to return to the streets of modern London.
