No, I did not click the "recommended" button by mistake, this tutorial is indeed fine.
But... Are we really asking newbies to download a tutorial? Where is the tutorial for that?
Makers, let's not forget that most players don't want to make their own game. They want a good game out-of-the-box and maybe just customize it or extend it after a while.
Imagine for yourself, someone tells you that "you have Notepad and you can turn it into a half-decent IDE by installing two dozens of plugins; you can be up to speed in a week or so. If you have issues with plugins fighting each other, seek help on the forum"... Chances are that you'll say "No thanks, I'll use VSCode".
"You have MTG and then you can make your own game by downloading mods, checkout out our huge ecosystem" obviously won't fly with most newcomers. It used to be Ok when users had to install mods and "subgames" manually, but not anymore (those people are modders now). To be fair, this is thanks to the efforts of the MT team and contributors. Don't let one old apple that turned bad spoil the barrel.
This tutorial should be shipped instead of MTG. Add to it a couple of lines to tell the players what to do from there at the end (how to get an actual game), then we are good and done.
I totally agree: this subgame should ship with the launcher, or possibly be integrated into MTG proper as the default map generated. Have an experience that all new Minetest players are likely to share and build upon.
