YTech
by lalis.jan
YTech turns the early game into a staged progression, starting with stone tools and ending at the iron age, and changes vanilla recipes along the way.
What it does
YTech slows down the opening of a world and makes the player use primitive technology before reaching iron. It adds a stone age that raises difficulty early on, and a bronze age that leads to the final step of crafting iron ingots. Vanilla recipes for early items are changed, so some tools and blocks have to be made in a new way, and the mod adds items and blocks that support the progression.
The standard animals met early in a world are swapped for wild ancestors, so the livestock differs from vanilla. YTech requires Forge or NeoForge, runs for Minecraft 1.20.1 – 1.21.3 and is published with source code and a wiki. Its files cover 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5, 1.20.6, 1.21, 1.21.1 and 1.21.3, and the mod is open source under the GNU General Public License v3.0 or later. Client and server both need it, so every player on a server runs it too.
Key features

Replaced wild animals
Livestock found in the world is swapped for wild ancestors, changing which animals appear early on.
Recipe and probe support
Recipes changed by the mod can be browsed, and blocks and block entities show extra information in the world.
