MINECRAFT

Vipe, you can build high walls pretty easily by standing on top of the place you want to put the block, looking down, and juping to place the block beneath you. You can go as high as you want this way, but if you're not playing Peaceful mode, be aware of fall damage (your HP slowly regenerates in Peaceful; although a far enough fall will OHKO you).

Between me and my friend we've created a pretty deep mine in the hill, found most ore aside from redstone and diamond , put a high castle wall with a walkway, a moat (work in progress), a watch tower and lighthouse, and an underground cavern with grass, a fountain, and a decently large library.

The time it takes to do stuff in multiplayer is better than halved!

diamond is rare and usually only found by lava, redstone is literally spawned about 6 blocks from the limit of the bottom of the map
