IDK a lot of the games feel really lame but there is this one CTF server that was fun. I might be too old for this stuff but I think it could be the next roblox if you could get it running inside of a webpage with WebGL.

Just scrolling through the list I found some interesting ones that really think outside the box (no pun intended), like this one that generates 3D-printable models.

Most mods are for minetest_game, so if you pick a different base you can't use them all. I always just added a bunch of mods on top of minetest_game.

I haven't played much myself, but VoxeLibre (and Mineclonia) are pretty good Minecraft replicas.

My only complaint is mobile controls. Desktop is decent but the mobile version (off F-droid) leaves much to be desired.

VoxeLibre is trying to be less of a Minecraft replica, now. Mineclonia still is, though.

Some subset of them does, many do not.

> And people playing Luanti play mods that replicate the original Minecraft?

Some subset of them does, many do not.

Can recommend Glitch. A fun singleplayer parkour game with a story.
