Civilian, industrial and advanced. Success rate drops and craft time climbs as you climb the tiers — and unlock costs jump with it. A recipe is an asset, not a consumable.
Bread, beer, furniture. Cheap to unlock, forgiving to run, and where every merchant starts.
Processed goods with tighter margins. One failed batch and the week is gone.
Long craft times, low success rates, high unlock costs. The tier that separates a workshop from a company.
A recipe you have researched cannot be taken away. Your competitors can copy the product — they cannot copy your cost base, your workshop throughput or your supplier relationships. Over a long enough run, that is the whole game.
