(Please note: I recived this from the Kickstarter as a backer.)
This is a solid set of Tools for players, and GM's. System neutral, but leaning heavily toward OSR. It builds on, and vastly improves upon the downtime rules from 5e. As well as adding a few twists of it's creaters devising.
That said, there are a few errors. I also feel the Profesinoal income section needed expansion.
I can safely recomend this book to others.
