I will eventually do an episode on the INIT files which will include that. I suppose I should do it soon... I didn't want to encourage people to do that right at the start, because once you turn off varied ground tiles, you get used to that and will never understand the original tiles (which I think look far nicer and sometimes provide more information about the tiles - and once you spend an hour or so with varied ground most people get used to it). But on the other hand, I'm very much all about accessibility, and I'm sure some people have legitimate reasons to prefer the unvaried ones, so I will certainly mention them when I finally get to the INIT files (I'll move them up the list a bit, since they are so important). And feel free to leave a comment on the video pointing out this option, so other viewers might see it. It helps my channel a bit as well when people leave comments.
The next two planned episodes are the status window (just a basic overview - this one is partially done) and the concept of jobs and labors (a much longer once since I explain what every labor does - this one is written but no recording has been done). Maybe I'll stick the INIT overview after that, or maybe even in between them, since after the jobs/labors one I plan to finally show how to do some specific things in game (building workshops, building furniture, setting up farms, etc.).
