The main thing holding it back as far as I can tell is the dead modding scene. Minecraft has the best modding scene of any game ever, hands down. You don’t even need to compete with that, just have a small modding scene and the game gets way better.
The minecraft modding scene is also a serious longterm threat to microsoft making money off minecraft, so I hope the Luanti modding scene continues to grow!
(I don’t think microsoft will necessarily kill java minecraft but microsoft clearly sees minecraft java as a dead end, you are fooling yourself if you think otherwise)
It does have a decently-sized modding scene, though? Like, it cannot compete with the popularity of Minecraft and therefore doesn’t have as many modders.
But it has a modding API, which makes it a lot easier to mod and means that the mods don’t break with every new version, so the effective output of those modders is actually pretty good.Or well, just look at it: https://content.minetest.net
Funnily enough, as Minetest/Luanti is written in Lua, it should be easy-ish, in theory, to import some of the simpler roblox games.
Then again, good luck bringing people from Java Minecraft or Roblox over to a FOSS alternative. “Nobody’s there”.
Can you import worlds?
This is the most recent and performant tool I have heard off, to convert Minecraft worlds to Mineclonia specifically.

I haven’t tested it though.
Hell yeah I love it!
