I destroy mountains, only to replace them with monuments of awesomeness. I destroy every enemy, hunt down every farm animal, clear away forests, all for my own benefit. My fortress of solitude spans the entire map, has enemies spawn inside of it, only to fall in one of my death traps. (Speaking of which, I need to check thoose. And there's A LOT of checking to be done. Like, 200+ holes I filled with arrow launchers)I have found enemy spawners and not destroyed them, but tamed them, so they don't spawn enemies. My most greatest achievement was most likely the time my stronghold that I built covered the entire map, including the big ocean that spans, well, a lot of the map.
