The first playing area of the game has a few really nice caves, dotted through the map that you can build in, explore, and have lots of room. But Siptah only has a few really small caves that are closer to crevasses and less like caves. It’s been a while since a new map was released, and I’m dearly hoping another one comes out. If you guys are working on a new map, PLEASE make sure it has plenty of deep caves for exploration/moving in to!
I really do think that caves are the biggest feature that are overlooked by developers. I did a search for Siptah caves after I explored for a while and couldn’t find any decent ones, only to find that lots of people were let down by the lack of good, roomy caves to build in on Siptah.
