Hello,
I stumbled over the mintest engine and games to be played with the minetest engine and wondered if it would be worth offering an own forum for it. (the engine and the game?)
https://www.minetest.net
https://forum.minetest.net
https://dev.minetest.net
https://github.com/minetest
Furthermore, there is a free Minecraft Pi game for the Raspberry Pi:
https://www.raspberrypi.org/documentati ... /minecraft
https://projects.raspberrypi.org/en/pro ... necraft-pi
What "free" exactly means, I have not investigated, though, but maybe it is different than the aforementioned minetest engine in this regard.
PS:
For those interested, it is possible to run Raspberry Pi OS on a Desktop PC or in a virtual machine:
https://projects.raspberrypi.org/en/pro ... pi-desktop
You can run e.g. Minecraft Pi there as well, and of course also the minetest engine and games. The Pi for Desktop OS is - AFAIK - a modified Debian.
