Would treehouses be a possible thing in cataclysm?
I’d presume not, due to every tree occupying a single tile and that’s it, but perhaps something similar to the simple shelter could be a thing. It could allow players to move into the tree’s tile and sleep in it, and of course giving them a level of coverage that would allow the player to hide from things but still permit a good sight range outwards. Good for hunters and hiders from zombies alike!
It makes me wonder if trees could be a multi-space and z-level object, it’s trunk being a single tile and then one level above there being a 5x5 space or so of tree space, depending on the tree species. If so then people could build a nice little space for themselves in the trees and players could also then use the trees to traverse forests in the canopy instead of walking through it if they have an introduced perk like acrobatics or something.
