Nomad SRD

The Nomad System Reference Document (SRD) is a free rule engine for tabletop role-playing games (TTRPGs) using two six-sided dice (2d6) for task resolution, with a small "pool" of additional d6s as modifiers. It is a skill-based system initially written for science fiction but easily modifiable to other genres. The Nomad Engine is published under the Creative Commons Attribution License v4.0 (CC BY 4.0).

This rule engine is used by Faster Than Light: Nomad, Stellagama Publishing's bestselling science-fiction game, and may be used by further rulesets by Stellagama Publishing in the future - and can be used by anyone else under the CC-BY-4.0 license!
