I made a Minecraft addon that gets rid of all the compasses and map icons, and spawns you somewhere random when you die.

And you can respawn anywhere within 130,000 blocks of the world origin. So basically, navigation is impossible and anytime you die, you pretty much permanently lose your builds. It's a very zen way to play. Sort of like a tiny step down from hardcore. Haven't published it yet but I probably will soon. I don't think many people would play it. But for me, just standing on a distant shore and knowing my builds are out there somewhere sounds awesome.
