Paulpack Core

Paulpack Core is the support mod for Concession, a French-language
GregTech progression modpack for Minecraft 1.21.1 / NeoForge.

It is not meant to be installed on its own. Everything it adds is driven
by the pack’s own configuration files, and without them the mod does
almost nothing.

                          — What it adds —

The Consortium shop. A searchable, paginated storefront opened with
/shop, whose sections unlock as the player settles each instalment of
the pack’s central debt. Prices live in a JSON catalogue; balances are
held by EconomyCraft, which the shop only ever reads and debits through
its public API.

The quest ledger. A data-driven quest book with a pannable, zoomable
tree, per-chapter artwork and paged descriptions. Chapters, quests,
tasks and rewards are plain JSON, reloadable in place. Progress is
per-player, stored with the world, and the server is always the judge.

Blueprints. Import a schematic from disk, read its material list, see
the price before you commit, position a hologram, then place it.

The pack’s materials and economy tools: six ore families with their
tools and armour, a sale wand and a counter chest for selling at scale.

                          — Requirements —

NeoForge 1.21.1. EconomyCraft is required for anything involving money.
JEI is optional: with it, right-clicking a quest objective opens that
item’s recipe.

                            — Status —

Alpha. The pack it belongs to has not been played end to end yet, and
prices in particular have never been balanced against real play.
