What has been your biggest minecraft project? Mines would have been me and a few friends recreated Blacks ops 2 origins zombies map and implemented a zombies game mode.
I built the Mines of Moria from Lord of the Rings once... In Survival. (Yes, I have no life.) Other than that, me and a friend has copied the pyramids Egypt on the side. I have also personally made a medieval city in gothic style on the size of Manhattan.
