If Roblox counts as a game instead of a platform, then I guess Minetest also counts as an open-source game.

Roblow isn’t a game. Minetest is an engine (providing it’s own API that game developers use to develop games), and a platform to distribute them. In a sense, Minetest is like Unity or Godot. Games built on Minetest include MineClone2/5, Nodecore, Exile etc.

Yeah, let me open up Unity for that vanilla gameplay experience, oh wait…

Also, are wc3 and hl also not games because they were used to develop and distribute games that ended up being more popular?

You cannot play default minetest without a game. It comes installed with minetest game (which is a crappy game and more of a modding base). Delete it and see if you can play, yeah?

What is wc3 and hl?

Sure, it’s a crappy game, but when you install Minetest you can play Minetest, and you install Minetest mods to mod the Minetest game. You can’t use Minetest mods on Mineclone. If you install unity you can’t play unity, you make a game in unity.

Warcraft and half life

Basically, you’re saying because an engine also has a packaging element (contentDB is the packaging and distribution part maintained by 1 developer, it cannot be an engine). It is both.

I’m more inclined to believe the team who make it rather than some random internet stranger though.

At what point did I say it’s not an engine? I’m just denying your claim that it’s not a game…

MTG - Minetest Game is the game. It’s in the name. Delete it, and you cannot play Minetest. Minetest is referred to as the engine. They renamed MTG and put it into maintenance mode because of the confusion. It was badly named initially. The team have already made the decision to remove MTG by default so it comes with no games. They are just waiting to redevelop the UI so it isn’t so painful when this happens.
