After playing some Dwarf Fortress, I got a very good idea.
1. What is Minetest missing?
Content. There is just nothing to occupy your attention when you start the game.
No great story to play through, no interesting combat, no satisfying shotguns.
Of course, MT sucks at combat. It's simply true of all the games of this genre.
Except maybe OpenSpades. Yeah.
Now, we can't really focus on combat. What else can we do?
Exploration! We can have player explore dungeons.
Why would the player do that, you might ask?
Because he likes doing such things. And because he can find recipes there.
Now, before you install this mod and go around searching for recipes, it's WIP for a reason.
No recipes yet. Sorry. You do start with some, just so that you can test the craft system.
2. Crafting in Minetest sucks aswell.
It's not boring, and it does work.
Problem is, player can always craft the same things. You can't prevent player from crafting
a diamond helmet because he isn't smart enough, or crafting a stone because he has no
hammering skill. You can't set your own requirements.
You will be able with this.
3. What is this mod for?
Subgames and servers. Don't expect it to ever be a fully-fledged mod on it's own.
That is, the ones that want to add some exploration/RPG skill building/etc.

When you close the formspec, it, of course, continues crafting:

Look at that pretty progress numbers.
World of Warcraft?
I tried to make it world-of-warcrafty. Like toolranks.
It's awesome! How can I help?
Thanks! You can find the git repo here. Feel free to make a pull request, or to contact me if you need help.
Oh, and you can also comment random feature ideas. I like those.
Or you can test the mod. That is cool, too.
