A Fallout tabletop role-playing game is being created by J.E. Sawyer, one of the makers of Van Buren, Black Isle's cancelled Fallout 3. It was started on October 23, 2004 (exactly 73 years before the Great War). Just like us, J.E. uses a wiki, but one in which only he can edit pages.
The character system is called Simple. It is a simplified version of SPECIAL without the Luck statistic. It includes Perks originally designed for Van Buren.
While Sawyer no longer works at Interplay and the game is not canon, it includes details about factions, locations and other plot elements from Van Buren, such as Caesar's Legion and Hecate, therefore such information may be considered semi-canon, just like Van Buren leaks, as long as it doesn't contradict further canon sources.
The system is not finished, not professional, and the author makes no claims that it is great or even good.
