Flex20

An RPG rule system developed from the D20 SRD, open license. Simplified combat rules. Two different approaches to classes: simple class archetypes or more advanced class templates.
Primarily for fantasy but can be used for any setting.
If you downloaded COMPACT20 or CONDENSED20, this game replaces those.
