Reality check: everything in Minecraft is useless
Popular society would try to have us believe that gaming isn't important, and therefore everything in a game is useless, but it one of the most important things humans do. The fact we do stuff just for entertainment's sake and not spend all our time either surviving or passing our genes on is what separates us from the animals. Sure, some other animals game a bit but their games are purely an extension to survival/hunting training. The life experience gained from gaming is much more useful than watching tv, but tv will never tell you that hehe.
On topic: I fell off a void world and lost my power suit yesterday, thanks to the greg recipe not being the only one (yet) I was able to remake it, would've been apathyquit worthy if I could only go the Gtech route.
