I've decided to add Nether to my minetest world, but not because I need more adventure. I just need a bucket of lava and I think it'll be easier to find in the nether than in the world. If I needed more lava I might not mind the search but all I need is one bucket for a basalt generator. I already have a bunch of obsidian from my melting furnace so I should be able to sneak in and out and have this wrapped up in no time. Later having the nether to explore will be fun anyway.
