Mercatorio Season 7
Season 7 of the medieval economy simulator Mercatorio starts on May 1st
and will include new buildings, new products and new production methods.
This time there are significant changes in transport operation and the
market mechanics related to that, as well as expansions of the chemical
industry of the Mercatorio world.
Product updates

From industrial chemicals to more nuance in kernels of crops, types of
fabric, to luxurious soap (though not without industrial applications).
These are the new products this season:
- Potash: Burning of large amounts of hard wood produces caustic potash
which can raise the pH of solutions or otherwise take part in many
chemical reactions.
- Tallow: Rendering of scraps left over at the Butchery produces a
greasy substance that can lubricate machines or be further processed
into eg. Soap.
- Soap: The reaction of Tallow and Potash produces an excellent cleaning
agent. Either for cleaning the body of people that care about such, or
for cleaning inputs or outputs of greasy production processes.
- Seeds: Flax seeds are now treated separately from other grain. Their
high oil content makes them good fodder for animals, but they can also
be ground up to extract the linseed oil for other uses.
- Varnish: Boiling and mixing of various oil or resins produce a liquid
that upon oxidation leaves a strong and waterproof protective layer on
whatever it is put on or mixed with.
- Canvas: Heavier and denser linen fabric that is more wind- and
water-resistant than regular cloth and more suitable for windmills,
sails or sacks for transportation or storage of dry goods.
- Acid: Distillation of either vinegar from sour wine or better, various
minerals, create strong acids that are helpful in separation of
different metals during smelting.
Other notable product updates:
- Candle bundles are increased in value and weight (doubled), while
storage and transport space remains unchanged.
- New and increased demand for Spirits and Medicine
- Many higher level production methods are now using Paper (for
templates or construction drawings).
- Cured Fish has been slightly boosted relative to Cured Meat.
Building updates
New buildings this season:
- Rendering House: Attachment to the Butchery which renders scraps and
leftovers into useful Tallow.
- Soapery: Mixing Tallow and Potash to produce useful Soap for
industrial or personal use.
- Bullion Forge: This new forge specialises in smelting of bullion
metals, gold and silver. Their smelting production methods are moved
from the Smeltery to the Bullion Forge.
- Canvas Weaver: Specialising in the weaving of strong and heavy canvas
fabric, requiring more sturdy equipment and processes than regular
Cloth.
- Distillery: Taking over Spirits distillation from the Apothecary to
handle increased demand for Spirits (and letting the Apothecary handle
new demand for Medicine), as well handling the new Acid production.
- Varnish Kitchen: Crushing of seeds, boiling and mixing the ingredients
required to produce tasty looking Varnish (Do Not Drink!)
Other notable building updates:
- The Cartshed is renamed Cartyard and a new, cheaper Cartshed is added
with lite versions of the production methods. Upgrades back into the
Cartyard.
- The Tapestry Weaver is renamed Tapestry Atelier and gets new
embroidery production methods.
- The Charcoal Hut is renamed Burner Hut and add gets new Potash burning
production methods.
- Cottages and Rowhouses are reduced in cost while requiring more inputs
for their production methods, giving an economic profile more alike to
other production buildings.

Transport updates
- All ships and carts are getting a “renew” operation method
facilitating simpler and more efficient large-scale trade. In this
operation the transport convoy relies on spare vessels maintained by
the ship or cart producer instead of doing its own.
- Trade in ships and carts is now possible to automate, both on the
market in your own region and others, assuming you have a trade route
to the region capital.
- Operation products will now be kept at the base of operation and no
longer reduce the available cargo space of transports. (Transports
linked to a warehouse already function like this and this will remain
as before)
- Transport trade range becomes a softer limit. Trade routes exceeding
the trade range for a transport will incur double cost for the
distance beyond the range. The hard cap is moved to 2x the trade
range. Tumbrel range is reduced from 1200 to 1000.
- Transport cap bonus from mercantile skill is increased by 1 for
journeyman and master (to 4 at journeyman and 12 at master).
- Hulk production cost increased, operation cost reduced.

for simpler and more efficient operation.
New Trade Route mechanic
Trade route total number of imports and exports are getting limited to a
transport type specific cap, plus modifiers from prestige and mercantile
skill.
Base transport slots:
- Handcart: 10 (up to 10 imports and up to 10 exports)
- Tumbrel: 16
- Snekkja: 14
- Cog: 20
- Hulk: 26
- Premium Cog: 30
Bonuses from prestige (+1 for each increase in transport capacity) and
from mercantile skill (+1 at worker, +4 at journeyman, +12 at master)
Other updates
- Town centre building expansion is relaxed to reduce crowding and
unnatural restrictions. They can be expanded across town quarters,
following the same mechanic as district buildings, with expansion
allowed to any available tile within a certain radius.
- Cultural leadership establishment growth cap is increased from 0.25%
per turn to 0.5% per turn.
- More tenants early on and slightly fewer at high prestige levels.
