It's very similar to styles of generating lairs/dungeons in many TTRPGs. A lot of them come with various tables/dice rolls to help build a layout and then subsequent tables to give a general prompt for what goes in said rooms. It's an extremely satisfying routine, as you're not 100% beholden to every dice roll, but the dice rolls help prime the creative juices and give constructive constraints to the process.
Playing hexcrawl RPGs like Twilight 2000 with my groups has been great. The physical edition came with a custom deck of playing cards that had encounters and randomization tools printed on them - I can literally just draw a card and immediately create an encounter for the players.
I highly recommend trying it out for yourself!
