So after seeing map walls on youtube let's plays and even more recently on this forum, I've started making a map wall myself to see how large my main base's domain is. Turns out its not really all that big. Size 1 maps are really easy to fill, and most of my operations fit in 2 of those. The rest is captured land for domain/tree farming purposes.
There's a jungle to the southeast I intend to add to this wall eventually, once I work up the spinal strength to cut down more of it. Fire is surprisingly terrible for the most bit, as it only takes out undergrowth and not most of the taller trees. In the mean time, I'm experimenting with ways to put down walls for keeping mobs out.
Fun facts: the sand-white streak in the middle is a gravel slab path. the sand-red/brown streak above it is packed earth. Jacklanterns seem to show up as green.
I'd like to see some other collections of maps everyone here has. My own collection is rather small atm, as is my domain.
