No, the above photo isn’t my own cavern/dungeon, but I have something similar and can add to it pretty easily.
But I’ve been wondering more and more lately about the use of terrain in my games. I love the terrain myself, but using 3D terrain makes the game play differently than using battle maps or my old digital desk. The terrain looks incredible and the ability to take tactics visually and intuitively into the third dimension is very nice, but the logistical activities that are involved in transporting, setting up, moving around, reconfiguring and otherwise messing with the terrain is something that impacts game time.
If you just put down the terrain the PCs can interact with as they move around then you are constantly adding, removing and shuffling heavy blocks of terrain around, knocking over minis, replacing them where they need to be, etc. If you put down a huge area of terrain (like above) then the players can see the whole area at once and that gives them knowledge the PCs don’t have, which can impact how they decide to explore an area.
One possibility is setting up a large area but covering it with something and removing the cover as the PCs explore, but that requires having the time to set up a large area in advance, which I will have to wait until I have my own gaming room to do.
What are your thoughts on using 3D terrain?
