Course Tech Trees

It’s kind of a weird concept, but maybe along with the program pages, instead of having an “Explore” page, you have a tech tree, with all the courses you can take, and then after taking them you can take the others. For example, you have to take Mindustry to take Factorio. If you have already done something like this, (E.g. you’ve never taken a mindustry cohort but have played before) you can talk to a guide, and they will give you permission to do it, but it will still be recommended that you take Mindustry first.
