Litppunk, I like this idea of adjusting spawn/evo rates as you progress, I’ll be giving that a try. As far as food goes…you should add cdda fantasy factions mod, nothing tastes better than goblin meat 
You may want to take a look at the combined itemgroups mod as well or your forests will become quite barren of anything but elves/orcs/goblins.
Was it just me or older experimentals that dont allow you to save world changes on your saves? I found it annoying having to go back to the world settings and change them each time i loaded the game.
Making a new world, my last survivor ate lead after his deathmobile vanished in the night(borked save)
