Star Wars Role Playing Game was published by Wizards of the Coast in 2000, and based on a version of the d20 system.
While it shared most features of the d20 system, roll over a target number, six ability scores, classes and feats, it also had some minor differences, including a wound / vitality system instead of a pure hit point system.
This first edition featured elements from the then new Star Wars: The Phantom Menace movie.
A revised release of this system was released in 2002; the 2007 Saga Edition would completely modify the system.
