D20 System
The current rules are based on the d20 System—a core set of rules which can be (and are) used as the basis for many games. Thus, many d20 games might use the D&D spell list, while others create their own or even replace the entire magic system.

Famous quotes containing the word system:
“The twentieth-century artist who uses symbols is alienated because the system of symbols is a private one. After you have dealt with the symbols you are still private, you are still lonely, because you are not sure anyone will understand it except yourself. The ransom of privacy is that you are alone.”
—Louise Bourgeois (b. 1911)
