There is certainly some psychological component at play. One of my favorite childhood memories is of me and my cousin digging tunnels for our hotwheels cars in a 10' mound of dirt my grandpa had hauled in. I recently tried this new Enshrouded game with another friend and we dug a tunnel for our base (for no reason). I just find it... cozy?

I think ancestral cave dwelling may for sure be a factor here, wrt evolutionary psychology (a scientific domain I wish was not as primitive)
