I feel like it would be interesting to make up systems that you can enforce through the debug menu.
For example, if you want to reduce food stores, make it so that you can exchange mass quantities for something else.
Also, you might want to give “colonization” a go. Set monster spawns to 50.00 (maybe lower upgrade speed) and head to a new section of map. Sure, it still requires travel, but it also gives you a fun challenge that in the long run, will take a long time to clear, while also avoiding any weirdness with hordes.
Heck, you could be lazy like me and not bother butchering or pulping corpses too. I don’t know how the horribly mutilated corpses still manage to revive, but they do make things very interesting, and make blade traps extremely useful.
