Procedurally crafted tools, no restrictions on build height, a massive view distance are all very cool.

I'll note that the well-established Luanti (formerly Minetest) has no restrictions on build height[1], but I have always wished I could get a longer view distance. And I've never seen procedurally crafted tools, but Luanti has extensive mod support, so I wonder if it would be possible.

[1] Okay, technically it's restricted, but the limit is something like a 64 km about a 62 km cubic space, which is much more than I could reach.
