SPECIAL

SPECIAL is the ruleset that powers all Fallout games. The name "SPECIAL" is an acronym for the primary statistics in the system: Strength, Perception, Endurance, Charisma, Intelligence, Agility and Luck.

Systems
Characters in SPECIAL are defined through Skills, Perks, and Traits.

Behind the scenes
Chris Taylor, Jesse Heinig and Tim Cain developed the SPECIAL system. Jason G. Suinn was responsible for pointing out that the acronym of statistics spelled "SPECIAL" as opposed to Cain's working acronym "ACELIPS."
