the interesting thing is the original aether mod was based on hidden sky dimension, using the same/similar terrian generation so technically world gen in aether is the same as the end.
These videos of yours are suuuuper underated! I am surprised the gears were converted ok to redstone, I knew they were the precursor but I would have thought they would have used different ids since they function so differently!
It did. The world generation technically changed to. The ocean of course changed drastically, but the land biomes changed very subtly. If you look hard enough you can find chunk borders between 1.12 and 1.13 terrain.
@@Kevin-no4ok it does exist in the game in late Beta Minecraft, it's just hidden in the game files. You can activate it with a mod like he does in the video.
