User summary:
minimald6 is a simple, fast-play system intended to support nearly any genre of roleplaying. Characters are defined by attributes and traits which may yield a situational bonus die to action resolution.
The core mechanic is a 2d6 (3d6 with advantage; 1d6 with disadvantage) roll against a static target of 5 or 6 for success.
A variety of genre-specific, concise games have implemented the minimald6 system; it is reproduced in each game (with occasional minor, genre-specific, modifications).
