If your goal is still to make worlds infinite you should add infinite world growth. I suggest the following -
*increase animal quality by 5 every time they rotate to ensure the world progresses(full moon phase).
*Bring up the Natural tree quality on new trees that spawn naturally by a chance to go up by 1.
* Add level 10 mine with Special Gems nodes that enable you to create a totem on mine 1 that adds 600ql to an area of rock, this will also reroll the type of ore in the area to another ore of a random type, inside that ore will contain a level 2(and so on) of the special gem that can be used on level 2 totem adding 650ql to an area. the first totem on a level will take 1*mine level to dry(like mine pyre) after that it's 1 day
