So I recently started a game with the “Wildlife Only” mod (and a few others), 0.5 spawn rate for mobs and NPCs, and an item rate of 0.15. This has made for a very interesting game of survival, having to constantly be on the move in search of food/water, and lacking the most basic of tools.
I think I even shouted in joy earlier when I found a manufactured hammer (You’d be surprised how many things need a hammer level of 3)
Try it out for yourself, and share you experiences (and joy at finding the most basic of tools)
