Build some cave-in traps for trolls and other nasty sieges. A support, with some walls above it. You can make this into a thick block, 3x3x3, and consume 27 wood + 1 mechanism, to make a death trap, although 9 of that wood will be recovered after the cave-in.
Alternatively, build something. Colored wood is fun to build with, or you can make it all charcoal and build in shades of gray.
I just might try that! A gray road is a neat idea.
I wonder, will this kind of stuff happen aboveground? I never actually tried that...
I think it will happen. I don't think that in the RAWs are some tree growth cap to prevent the map from being overrun by the flora.
make the trees into potash and fertilize your crops for 4x the plump helms
nah, I would have to get space for the potash AND the additional food. Hell, I'm almost ending the starving in my world with so much additional food and i'm still trying to decide how to maintain an reasonable rate for food production.
Yes, but it's not like the wood in trees is a huge FPS killer, you can't really have too much in that sense.
And any other negatives you can easily makes. For example, you could make a path with the road to all the open edges in the cavern so that anything that arrives won't find itself stuck in trees (and blocking some of the edges with walls if necessary). There aren't usually that many potentially entries underground, and honestly, paving is not that slow.
Aesthetics I call your problem =P
Building in the edge of the map isn't possible, am I right? Aboveground I can't put walls or floors or roads on the edge of the map, at least.
and paving is slow when the stockpiles are far, and the masons and architects are building a lot of roads in several places at the same time.
And yes, aesthetics is one of the problems. I want a cavern look like a cavern(with monsters and caps, alright, but not a LOT of them) not the mushroom kingdom overgrown.
