Kinhold — Systems and content analysis

Version 1.2 · 26 Oct 2026 · Based on GDD v0.9 · Complements the analysis document (catalogue)

DECIDED comes from the GDD PROPOSAL new content or value for your approval MISSING not defined yet QUESTION yours to decide

All figures (times, yields, capacities, durabilities) are starting values to be tuned through testing. None has been verified in play.

1. Diagnosis: what we had and what was missing

GDD v0.6 has the rules of each system. The analysis document had lists of content. What almost all of them lacked was the concrete workings: which tool gets each thing, how much it yields, at which station it is made, what it costs, how long it lasts. This document covers that as far as needed to start and move forward.

System	Rules (GDD)	Content	Concrete workings	Now
Gathering	Yes	List	MISSINGtool, action, yield	Section 3
Hunting and fishing	Yes	List	MISSINGbutchering, products	Section 4
Agriculture	Yes	Table by climate	MISSINGsowing cycle, tending, harvest, processing	Section 5
Livestock	Yes	List	MISSINGfeeding, breeding, products	Section 6
Technologies	Yes (by stations)	List of stations	MISSINGtiers, cost of each station, what unlocks what	Sections 2 and 7
Crafting	Yes	Chains	MISSINGrecipes with inputs and outputs	Section 8
Building	Yes	List of pieces	MISSINGdimensions, material, weight, capacity	Section 9
Survival	Yes	—	MISSINGrates of hunger, thirst, cold, fatigue	Section 10
Durability and decay	Yes	—	MISSINGfigures	Section 10

Combat and wounds	Yes	Healing	Defined while testing the duel milestone	Pending
Horses, ships, cartography	Yes	Partial	Detailed when their milestones arrive	Pending

2. Technology tiers APPROVED (provisional)

The GDD says progress runs from the Early to the Late Middle Ages through stations, and that the boundary stone is upgraded with materials of the technology tier. For both to work, concrete tiers are needed. I propose five:

Tier	Period	Entered by building	Typical materials (for the boundary stone)	What it unlocks
N0 Survival	—	Nothing: it is the start	Sticks, loose stone, fibre	Stone and flint tools, campfire, branch shelter, cord, firewood frame
N1 Settlement	Early (first half)	Log workbench	Logs, branches, reeds, mud, rope	Log and wattle huts, basketry, basic tanning, drying rack, first plots
N2 Iron	Early	Bloomery	Charcoal, wrought iron, planks, leather	Iron tools and weapons, forge, loom, pottery, hand mill, palisade
N3 Stone	High	Lime kiln	Lime, ashlar, mortar, roof tile	Rubble masonry and ashlar masonry, stone castles, watermill, mail, crossbow, boats
N4 Steel	Late	Blast furnace	Steel, glass, bronze	Plate, longsword, cranequin crossbow, trebuchet, large ships, glass, cartography

Each tier is entered by building a specific station, and that station needs materials from the previous tier. This way progress feels natural and there is no tech tree to memorise.

3. Gathering: what, where, with what and how much PROPOSAL

Item size (decides the slot): S small (belt), M medium (hand or container), L large (two hands, back), H huge (dragged, cart or several people).

Net	N2	Wide rivers, coast, boat	Bigger catch

5. Agriculture: sowing and harvesting PROPOSAL

DECIDEDOne season per real month; yield by climate band (good, poor, unviable).

The cycle

Seeds. Three sources: wild plants of your biome (wild cereal and pulses, wild vegetables), NPC merchants (seeds from other bands) and keeping part of your harvest.
Prepare the plot. The unit is a 2 × 2 m crop tile, on the same grid as building. With a hoe it is prepared tile by tile; with a plough and a draught animal, several at once (for large fields).
Sow in season. Each crop has a sowing window. Outside it, the seed does not germinate.
Tend. The biome's rain waters on its own; in the south, in summer, you must water with a bucket or an irrigation channel. Manure from your animals increases yield.
Grow. The crop advances through visible stages (sprout, growing, ripe). If winter arrives in the north before harvest, it is lost.
Harvest with the right tool (table).
Process the harvest to make it useful (threshing, milling, drying, retting…).
Store seed for the next sowing and the produce in a granary or storehouse.

Crops: sowing, harvest and processing

Crop	Sowing	Harvest	Tool	Processing	Product
Wheat, rye (winter)	Autumn	Summer	Sickle or scythe	Sheaves → thresh on a threshing floor with a flail → winnow → mill	Flour, straw, seed
Barley, oats (spring)	Spring	Summer	Sickle or scythe	The same; barley also for ale	Flour, grain, straw
Flax	Spring	Summer	Pull up by hand	Ret in water → dry → break → hackle	Flax fibre, linseed
Hemp	Spring	Summer	Sickle	Ret → dry → break	Fibre for rope and coarse cloth
Peas, broad beans	Spring	Summer	Hands	Dry → shell	Dried pulses
Chickpeas, lentils	Spring	Summer	Hands	Dry → shell	Dried pulses
Turnip, cabbage, onion	Spring or summer	Autumn	Hands, knife	—	Vegetable (spoils)
Hops	Sapling, once	Autumn every year	Knife	Dry	Hops (beer)
Apple, pear	Sapling, once	Autumn, from the second game year	Hands	Press (cider) or eat	Fruit
Vine	Cutting, once	Autumn, from the second year	Knife	Press → ferment in a barrel	Grapes, wine
Olive	Sapling, once	Winter, from the third year	Beat with poles + hands	Oil press	Oil, olives
Fig, almond	Sapling, once	Summer/autumn, from the second year	Hands	Dry	Dried figs, almonds

A game year is 4 real months, so a fruit tree gives its first harvest after 4–8 real months: it is a long-term investment, as in real life.

Calendar (north)	Spring	Summer	Autumn	Winter
What is done	Sow spring cereal, flax, pulses, vegetables	Harvest cereal, flax, pulses	Sow winter cereal; harvest vegetables and fruit	Nothing grows; live off what was stored

In the south winter is mild and the problem is summer drought: there you irrigate.

Rule	What it is
DECIDEDFallow	Repeating the same crop on the same tile yields less each time. Leaving it fallow for a season (or sowing pulses) restores it.

6. Livestock and breeding PROPOSAL

Get an animal (tame it in its biome or buy from an NPC merchant) → pen it (fence, pen, stable) → give it food, water and shelter → produce → breed (male + female).

Animal	Eats	Needs	Produces	Breeding (gestation)
Hen	Grain, scraps	Henhouse	Eggs (every game day), feathers, meat	Broods eggs: a few real days
Goose, duck	Grain, pasture	Pen with water	Eggs, feathers, meat	The same
Pig	Scraps, acorns (forest)	Pigsty	Meat, fat, leather	One season
Goat	Pasture, branches	Pen	Milk, meat, hide	One season
Sheep	Pasture, hay	Pen, sheepfold	Wool (shear in spring), milk, meat	One season
Cow, ox	Pasture, hay	Byre	Milk, meat, leather; the ox pulls the plough and the cart	One and a half seasons
Donkey, mule	Pasture, hay	Byre	Carrying with a packsaddle, light draught	One and a half seasons
Horse	Pasture, hay, grain (for hard work)	Stable, horseshoes (N2)	Riding, draught, carrying	Two seasons; heritable traits
Dog	Meat, scraps	—	Guarding, hunting, herding	One season
Bees	Nearby flowers	Hive	Honey and wax (summer and autumn)	New swarm in spring

Pasture: animals in a meadow eat the grass, which grows back; if there are too many for the size of the meadow, it runs out and they must be given hay. Hay: grass is cut with a scythe in summer and dried for winter.

If neglected: without food or water, the animal falls ill and stops producing. DECIDEDIt does not die: once cared for again, it slowly recovers. Calculations are based on elapsed time, so this happens even when you are away.

10. Values for each system PROPOSAL

One game day = 3 real hours (2 of daylight, 1 of night).

Survival

Need	Rate	Warning	If it reaches the maximum	Recovered by
Hunger	You must eat 2–3 times per game day	Orange circle	Faster fatigue, then slow wounds	Food; cooked food is more filling
Thirst	Faster than hunger	Blue circle	The same, faster	Water, milk, ale
Cold	Depends on biome, season, night, rain and clothing	Light blue circle	Clumsy movement, fatigue, slow wounds	Fire, roof, clothing
Heat	Depends on biome, season, sun and armour	Red circle	Faster fatigue and thirst	Shade, water, light clothing
Fatigue	Rises when working, running, carrying, fighting	Grey circle	You cannot run or strike hard	Resting seated; sleeping fully restores it

Durability

Item	Stone / wood	Iron	Steel
Axe (mature trees felled)	~3	~30	~60
Pick (quarry blocks)	—	~40	~80
Weapon (blows taken or dealt)	~50	~400	~800
Clothing and armour	Wears out when taking blows and with use; repaired at its station with its material

Decay and upkeep

Material	Without upkeep, starts to fail after…	Disappears after…	Kept up with (in the boundary stone)
Straw and reeds	~1 real week	~3 weeks	Straw
Untreated wood	~2 weeks (less in damp areas)	~6 weeks	Wood
Treated wood (pitch)	~5 weeks	~12 weeks	Wood + resin
Stone	Never disappears: remains as a ruin	—	Lime

Boundary stone consumption: a small amount per real week according to what is built (for example, 1 unit of each material for every 10 pieces of that material). So a hut is kept up with a couple of logs a week.

Boundary stone

Level	Upgraded with	Land radius	Exclusion radius
1	Placing it (3 stones)	20 m	300 m
2	N1 materials (logs, rope, mud)	40 m	500 m
3	N2 materials (iron bars, planks, leather)	80 m	800 m
4	N3 materials (lime, ashlar)	150 m	1,2 km
5	N4 materials (steel, glass)	250 m	2 km

Death

Roughly half of what you carry stays on the body to be looted; the other half breaks, chosen at random.
The body lasts for a while (for example, 1 real hour) and then disappears with whatever is left.

Hired NPCs

Type	Pay	Eats	Needs
Mercenary / sentry	High, per real week	2 rations per game day	Weapon, armour, bed
Woodcutter	Low	2 rations	Axe
Day labourer	Low	2 rations	Hoe, sickle
Shepherd	Low	2 rations	Crook, dog (optional)
Messenger	Per journey, by distance	—	—

11. A player's first day

A check that everything fits together: what someone does in their first session with what is defined above.

Appears in a linen shirt and trousers, barefoot, at an accessible spot in their region.
Thirst warnings: finds a river and drinks with their hands.
Pulls up fibre and makes cord; ties the cord on as a belt (1 slot).
Gathers flint and stone, sets up a knapping stone and makes a flake and a stone axe.
Gathers branches, makes a firewood frame, lights a campfire for the night.
Plants their boundary stone (3 stones) and builds a branch shelter, which binds as a bed.
With the fire-hardened spear hunts a hare, butchers it with the flake and roasts it.
Fells a young tree, makes the log bench and enters N1.

No step needs anything that is not defined. From there on: the log cabin, the basket, the spade and the first crop tiles.
