There are two variants of the system for
Ex Machina;
Tri-Stat d8 and the
d20 System.
Tri-Stat d8 Under
Tri-Stat the game uses point-based character design and a two-die task resolution system. The game engine focuses on story over rules, and is known for its flexibility.
d20 System The
d20 System variation combines the points-based special abilities of
Tri-Stat with the classes and levels of
d20, and uses a hybrid task system mostly built from the
d20's single-die high-roll method. The
d20 variant is based on the
Big Eyes, Small Mouth game system. This variant is solely a fan-based production, and not endorsed by "Guardians of Order". ==Current status==
