The Exodus System is a simple game with a lot of good ideas in it. Some of the most innovative gaming ideas of recent history have been elded to a simple OSR sensibility.
Characters are built on atrribute dice, a Professional Selection, A combat Mode Selection, Two Flavors (these are packets of "Cool things" similar to Cypher System's Foci), and a set of skills.
Task resolution is simple and fast, like most OSR titles. Ther are also some tables and suc h to aid with adventure design ideas for GMs stuck for an idea.
The material inside has what is needed to play, but I am sure anyone who reads it is going to be inspired to craft a few Flavors of their own, and I am sure that is exactly what Mr. Ross wants you to do. Indeed, the first supplement showcases a custom flavor to give mechanical advantages to centuar characters.
There is some very nice art in the book and the layout is clean and sharp. Thunderegg has been very repsonsive adding features and options to the PDF to make it more useful, and that shows a great repsect and dedication to their customers.
