Oh yes, that is always my favorite method. My first ever base was built into rock, and I’ve been doing it ever since. I did use the tree interior of a hill as a temporary home once, though there simply wasn’t enough trees in it to properly build a wooden home. I do hope that, once I finally learn how to get a w(he)aystone and a deed (or just make the half a year trip back), I’ll be able to relax enough to build proper homes with my own hands. After months of in-game time (days of irl time) running for my life, it will be so rewarding to finally do some build projects. The dominion soldiers may not appreciate good architecture, but I do!
