Hand crafting

The player holds an inventory of components and a set of known recipes, each mapping an input multiset to an output item. A craft checks that inputs are present, any required station (workbench, forge, furnace) is nearby, and the recipe is unlocked, then consumes the inputs and produces the output instantly or after a short delay. Minecraft uses a 2x2 grid in the inventory and a 3x3 grid at a crafting table, with shaped recipes keyed to spatial arrangement; Don't Starve, Valheim, and Subnautica use menu lists gated by stations and blueprints; Ultima Online ties success to a crafting skill. Infinite Craft replaces the recipe table with a language model (Llama 2, later Llama 3.1) that generates the result of any new pair and stores it so every player gets the same answer. Inputs: carried items, station proximity, unlock state. Outputs: new items and consumed components.

Gathering with intent. The player looks at a desired item, works back to its components, and goes out to collect them, so the recipe list becomes a shopping list that structures exploration. The first craft of a new tool is a small power spike that opens the next zone or task.

• recipe count and depth of intermediate components
• discovery model: all visible, unlocked by research or blueprints, or found by experimentation
• station gating and whether stations must be nearby
• craft time and whether crafts can be queued or batched
• spatial grid versus list interface
• inventory limits that bound how much can be carried to a station

• Hidden recipes without in-game discovery aids push players to wikis, as in early Minecraft before its recipe book.
• Long chains of trivial intermediates turn crafting into inventory sorting.
• Crafting that is strictly better than found loot, or strictly worse, makes one of the two systems irrelevant.

• Tool tiers gate access to materials, which gate the next tool tier, producing a progression ladder from rules alone.
• Inventory limits couple crafting to base building and storage chests.
• In multiplayer worlds players specialize in crafting lines and trade, as Ultima Online crafters did.

• Can generative models produce open recipe spaces like Infinite Craft whose outputs also have balanced, mechanically meaningful stats rather than only names?
• How should discovery be explained to players when a model rather than a table decides what a combination yields?
