Andesite Age

A Create-focused vanilla+ modpack for Minecraft 1.21.1 on NeoForge.

Status: beta. Playable end-to-end and server-validated. Balance has
not been road-tested by a full group yet.

The pitch

Most Create packs bolt Create onto a kitchen-sink tech stack and let
Mekanism, Thermal, or AE2 outscale it by mid-game. Andesite Age goes
the other way: Create is the industrial backbone, and nothing in the
pack is allowed to trivialize it.

Every mod passes two filters before it gets in:

1. Does this trivialize Create's role? No parallel tech trees, no
   alt power systems, no mod-added quarries or magic-box ore doublers.
2. Does this break the vanilla world feel? No aggressive worldgen
   overhauls. Modern vanilla worldgen is good enough; we add to it, not
   replace it.

What you get is Create + a curated set of Create addons, plus a thin
layer of QoL, performance, and vanilla-gap-fillers.

What's deliberately out

• Mekanism, Thermal Series, AE2, Industrial Foregoing, and other
  parallel-tech stacks.
• Mod-added quarries, digital miners, and ore-doubling shortcuts.
• Terralith and other aggressive worldgen replacements.

Requirements

• Minecraft 1.21.1 · NeoForge 21.1.227 · Java 21
• ~4–6 GB RAM for the client; similar for the server

Installing

Client. Download the .mrpack from this page and import it into
Prism Launcher, ATLauncher, or any MultiMC-family launcher. They handle
mrpack natively.

Server (Docker, via itzg). Minimal compose:

services:
  mc:
    image: itzg/minecraft-server
    ports: ["25565:25565"]
    environment:
      EULA: "TRUE"
      TYPE: MODRINTH
      MODRINTH_PROJECT: andesite-age
      MODRINTH_VERSION_ID: <pin-a-specific-version-id>
      MEMORY: 6G
    volumes: ["./data:/data"]

Pin MODRINTH_VERSION_ID explicitly so a pack update doesn't silently
change the mods under a live world. Client-only mods are tagged in the
mrpack and itzg skips them on server installs automatically.

Known issues

A handful of harmless upstream warnings fire during boot (class-load
noise from @OnlyIn references in certain mod mixins), and four
advancements fail to load in When Dungeons Arise and Dungeons and
Taverns — players just won't earn those four specific achievements.
These will self-fix when the upstream mods update.

Report real bugs on the
issue tracker.
