Used to be a must-have for underground exploration

This mod used to be the thing that made caves more than just boring tunnels with no life or shape to them, especially on 1.12. Yung's caves basically did caves and cliffs before caves and cliffs, however that does mean on new versions it is a bit less impactful.

On new versions, Yung's caves can be less impactful, but can still be a nice to have in cases where caves and cliffs doesn't quite cut it. I don't often use this mod on new versions anymore, and my review is left mostly for the old versions as I feel it is a disservice to rate the mod down because it was so good mojang implemented half of its ideas as vanilla features.

If you are playing 1.16- use this mod for interesting caves, on modern you might need to see if it fits your pack as not all packs need it anymore.
