I used to do things like this when I was a kid (less extreme, never more than a single sheet of paper), where I would create some natural features: a lake shore or river, maybe a freeway or two or a railroad and then start platting out a subdivision in the open spaces. It was a delightfully meditative practice and maybe I should start doing it again.
Same here. Was so bored I started drawing maps and inventing little stories in my head.
I think what inspired this was the LOTR in paperback that my sister had, because it had maps inside the cover.
you might enjoy cities: skylines
Not the person you replied to, but like them, I too liked to draw imaginary maps when I was a kid, mainly of medieval towns. I also tend to like the world-building aspects of strategy games, arguably more than the actual strategy parts.
Cities: Skylines have been in my wishlist since shortly after it came out but I never got around to playing it until about a month ago, and... didn't like it at all. It felt too "micro-manage-y" (for the lack of a better word) while also having the pressure of the ticking time.
Needless to say, I was very disappointed after looking forward to it for ~10 years.
I actually had the same experience as you (own it, played it only a bit for similar reasons), but FWIW I believe there is a sandbox mode to just play around in.
Another chill medieval town building game is Manor Lords. It has some management but overal is laid back.
I should check that out. Thank you
