Well for me it was letting my kid lose on our shared world.. my ideas usually run along the lines of clean and expansive. His ideas are more organic.
The bottom half of that pyramid you see in the first picture used to be an actual pyramid, and extends very far underground as well. To me having the huge expanse of inside in geometric perfection was pleasing.. He's turned it into an organic area filled with trees, lakes, rivers, lava pits, beds, and random stacks of random blocks everywhere, random chaos. So I don't want to work on my pyramid anymore lol.
However we were having fun
minecart boosters last night.
