does something like AllTheMods 10 exist for Luanti? Or Meatballcraft?

The Luanti client lets you search and install mods from content.luanti.org

It differentiates between mods and games. A game changes the core game to be much more different, but sometimes a game is just a collection of some other mods.

Personally, I find it more fun to just go and click on about 6 to 8 mods that are interesting and see how the game goes.
