I’ve written simple rules for generating a hex map, either in advance or on the fly (which works particularly well for solo play). The generator uses a simple system for taking adjacent hexes into account to avoid being totally random. Feel free to let me know if you have any feedback.
Oh, my bad. I added the link to the post, but when I also added an image the link was replaced by a link to the image it seems. Anyway, here’s the link: https://www.ttrpg-hangout.com/2d6_hexmap_generation_system.html
