I have been playing since late 1.12. I got my Xbox account in super late 1.13 just for Minecraft, although I have done more with it later. I got Java in late 1.14. I have been active in servers such as Cubecraft and The Hive. About 4 years ago, in mid to late 1.14, I created a world called Town, which I still play on to this day. In 2021, I joined a world called Mighty Kingdoms, where I created the country of Moria. Mighty Kingdoms was created in 1.17 with experimental 1.18 generation. We explored parts of the world in weird ways, making the terrain generation in MK super glitchy and unique. I'm 99.9999% sure you can't get the same generation in 1.20.
