I’ve started building a rather large underground lair and have used quite a bit of machined iron and copper
Very much a work in progress and one I’m quite enjoying.
This has caused me to become top dog of Chisel Town (more about that here
Was my sole purpose to build prestige to become viceroy. nope.
Was I going to hold back on mats used. nope.
But I have to admit I did quite enjoy getting the achievement 
It might be “lame” or whatever but I certainly didn’t do it to upset anyone.
I recognise Karokendo as leader of chisel town and will respect his wishes as to what to do.
I’m hoping we will all band together and go go city status, but who knows.
Building a hole or whatever just to fill with prestige blocks seems a waste…could always try to make a giant bit of art…even if underground.
