Before i was a significant builder, i used to go to my friend's house who owned blockland. There, before any experience, i learned that if you made a roof-less building with all the baseplates connected you could duplicate the floor. Then with a connection of macros and duplications, you could make a sky scraper in a matter of seconds.
After that started, we had a battle to see who could go height, mass, and still make it intricate and nice to look at.
height - IamBeef
Mass - Skymaster
intricacy - Skymaster
I was then the master of sky scrapers, so instead of using that name, just used SkyMaster
and i'm still working on a new skyscraper, but i'm not using the duplicator AT ALL
