It is best to think of Minetest as more of a decentralized open source roblox instead of a minecraft clone as one may initially think since it is more of a game engine than a game.
This is a pretty good way to put it. There are some similarities to Garry's Mod as well. All three are moddable with lua, and Garry's Mod's approach to mods on servers where you connect and automatically download what's needed is more similar to what Minetest does than what modded Minecraft does (where you need to prepare the exact right set of mods ahead of time or you can't connect).
