In RimWorld, the tech tree is the conceit which allows the game to work with its ‘societal drift’ conceit. Tribes of nearly cavemen, “modern” colonies, and ultra-tech feudal lords all coexist thanks to a set of technological ‘research projects’ which separate each colony by level of development. In our System Hack, we’re going to need the same tech tree conceit, but the underlying mechanics are going to be quite a bit different.

Before we go any further, I want to make sure you know that Cortex Prime is now available on DriveThruRPG. While digital versions of the game have been available before, you can now finally own a PDF version unfettered by a walled garden app which made the game significantly less accessible. With Cortex Prime finally available in the broader ecosystem, my hope is that there’s much more interest in this and a whole host of other projects using the system.
