Hi all,
I'm a wanna-be computer game programmer and have decided that I want my first attempt at making a PC game (for personal use only, of course) to be based on the Birthright Campaign Setting. (Sort of like a Birthright: The Gorgon's Alliance remake.)

Unfortunately, I'm not very familiar with Dungeons and Dragons or Birthright outside of that afore mentioned PC game.

Can any of you suggest a good place to attain a copy of the rulebook so I can get myself more acquainted with the rules?
