My proudest Minecraft creation was a shack on top of a mountain. It had a single room, a bed, a chest and one glass wall that looked out across the world as far as the draw distance could see. It was a terrible little box but it was my terrible little box. I look at some of the architectural wonders and recreations that people make and I think to myself, 'that is incredibly impressive and it is also something that I will never ever have the patience to do'. The same is true of the EverQuest Next Landmark video below. A piece of concept art is recreated in the game, the whole thing shown in time lapse. I want to walk around a world and see things like this but I'll be in my shack, with a telescope, watching the ants at work.
I could probably just about manage to recreate that.
