Also Modded Minecraft is extremely popular, and the mods necessarily aren't version agnostic, so you need to be able to run a specific Minecraft version to play the pack of mods you're currently enjoying.
Right now I am playing Enigmatica 2: Expert, which is a mod pack for Minecraft 1.12
Today I need to teleport to my spaceship which is in orbit around a distant planet and then fly it back to our solar system and visit Mars, as I have neglected to obtain materials from Mars which I need to build this end game item I'm working on.
It's still recognisably Minecraft even though I'm working with a 9x9 crafting grid. It has internal consistency, dragons hoard rare metals, Plutonium is a rare metal, therefore make sure to bring hazmat handling equipment if you're about to plunder a dragon's hoard.
