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.

Btw, mineclone2 also rebranded as Voxelibre, months ago, and for the same reasons. Voxelibre now actively moves away from copying Minecraft exactly.
If you want the closest copy (and my personal recommendation) check out Mineclonia.

Valve is holding the carrot, Microsoft the stick.

Friendly, and unsolicited reminder that the Minetest engine + its game Mineclonia (or alternatively Voxelibre) are a pretty good open source alternative as of late.
Minetest is also getting some pretty nice upgrades to its graphics lately. The upcoming release should be looking quite pretty.

My contribution to the discussion is that the Greek phrase for “(in) my ass”, if said in a hasty/hillbilly way, sounds pretty similar to Gollum. Might even call in to question the true nationality of this game’s visionary inventor.

Android is at 52%, desktop linux at 4% if you count desktop + mobile.

It says desktop in the image, I assume if it counted android it would be over 50% since apple is not as popular here.

The standard shell on the steam deck can be a bit creaky if you put pressure on certain points. How’s the new one?
