I’m aware that it is just an engine. And the point still stands - OP is asking how to play a specific game in Linux (Minecraft), and gets a reply like “play that engine instead” (Minetest). The reply does not specify which game (Minetest modpack) the replier sees as an alternative, nor addresses the fact that even the closest equivalents (probably MineClone2) are considerably inferior to the game OP is talking about, and thus not really a good alternative.

Please, note that I’m not singling out the person who suggested Minetest - I’ve seen other posters across other platforms doing the same. Frankly it feels like the people recommending Minetest as an alternative to Minecraft never bothered playing either for more than fifteen minutes.
