It doesn't get any emptier than this.
No matter how far you go, everything is VOID and SPACE. With about 6.5 ✕ 10^8 void blocks, that's more than a TRILLION. The best part is that now, you no longer need to excavate anything.
Finally, you can finally have a professional world, with no floor or rugged landscape in the way! It's perfect for those who are making any sort of non-survival world game.
