Learn how the Steam Full Release’s systems work. Each one links to the guide that explains it, beside the database that lists what is in it and the tools that answer a question about your own save.
What are you trying to understand?
Pick what you are trying to do and this page opens the guide that explains it. Systems this build cannot open yet are not offered.
Where the progression guide itself says when a system opens, this is what it says — quoted rather than paraphrased, because the timing is the part a reader must not be told wrongly.
Alongside the main route
Ranch
Day 5, alongside the main route
The Ranch system opens on Day 5 after you have spoken to Farmer Hans.
Three different jobs, kept apart on purpose: a guide explains how a system behaves, the database lists what is in it, and a tool answers a question about your own save.
Understand the system
Read the guide when you want the rules: how it starts, what affects it and what it feeds into.
