I'm playing survival, I've built everything else in this world legitimately. There's one small desert that I like the look of and don't want to completely destroy, otherwise I don't have a whole lot of sand.
Sand generators don't feel like cheating to when you have to legitimately discover red stone and slimed and set up a complex circuit to make it work. Plus I already built a warehouse for it labeled SandMaster 9000.
If I can't find a working one, I'm just going to have to dig up my desert, lay down some dirt under it, and cover the top layer up again, I guess.
