The d20 system is the game engine that certain pencil and paper RPGs such as Dungeons & Dragons or d20 Modern use. It is called such because most of the games rolls are based on a d20. The d20 system is also the basis on which the Open Gaming Licence, a ruleset that is free for anyone to use, is based on.
