1. Would love to see Tangy's twist on Skyblock! Maybe a bunch of planet fragments?
2. A war-torn world with active weapons still strewn around, including BUD-Activated TNT traps maybe
3. A world that's hollow. Maybe a Swiss cheese of stone topped with 3-5 layers of loose materials.
Finally, a super-dense jungle, and a heavily-flooded amplified world.
Anyone got ideas?
