My current project was,at the start,just me trying to find better ways to make massive mines.But then,I saw that the area in which I made my mine entrances was a nice little bay,so I made a portal to the netherworld to take netherrack and make a massive wall around the bay,complete with watch towers and a small submarine base looking building.
Now I'm just going to build an entire port.I have plans drawn up for the castle overlooking the harbour and couple houses and shops.I just finished a chapel,which was really a spur of the moment idea when I saw a huge pile of dirt blocks in one of the corners of my wall.
The real problem now is getting enough light inside the walls to not have creepers roaming in there,considering that I'm going to put block of TNT in storerooms next to prop cannons.One creeper there,and a third of my town would go up in flames.
As a stress reliever when I die of falls and lava from the netherworld,I have a 20+ tree forest and a chest with a couple lighters.
