Land Sectors

The game consists of a two dimensional regular grid of land sectors. Each sector consists of a type, a population, and a list of buildings. The type of a sector is unknown to the player until the player "explores" the sector. After that the player can transfer population to the sector and build buildings in the sector.

Initial the population in a sector is one and there are no buildings.

The basic types of sectors include Mountain, Prairie and Forest. Each type has different behaviors. In the future, additional sectors may be added to the game.

Mountain
- Resources Harvesting (per idle population unit)
  - Wood 0.25
  - Food 0.00
  - Gold 1.00
- Special Rules
  - Population in the mountains is limited to 100 people.
  - The population consumes .5 food per person per season.
  - Mountain people only reproduce in the fall, and only if there has been no starvation in that sector in the last year. The reproduction rate is .33.
  - Due to extreme weather conditions there is no production in the mountain in the winter. There is no resource harvesting in the winter.
  - During the spring a mountain generates 0.1 * population in gold.
  - During the fall, production is cut by 1/2 due to preparation for winter.
  - There is a limit of 5 production buildings on a mountain.
Prairie
- Resources Harvesting (per idle population unit)
  - Wood 0.25
  - Food 1.00
  - Gold 0.00
- Special Rules
  - Prairie people reproduce at a rate of .1 per season.
  - There is no limit on prairie population.
  - If the population exceeds 1000, natural resource production drops to 50%.
  - The population consumes .2 food per person except in the winter when they consume .6 food per person.
  - If the number of buildings exceeds 10 resource harvesting drops to 20%
  - In the winter, production in buildings is increased by 10%.
Forest
- Resources Harvesting (per idle population unit)
  - Wood 1.20
  - Food 0.30
  - Gold 0.10
- Special Rules
  - There is a limit of 200 people in a forest.
  - The population grows by 30% but only in the winter.
  - The population consumes .3 food per person in the spring and summer, .1 food per person in the fall and .7 food per person in the winter.
  - In the fall, forests produce .4 extra food per person.
  - Mints and factories can not be built in a forest.

Sector Actions

Each seasons, sectors perform the following tasks in the given order.

All sectors compute population change.
All sectors produce goods based on population and resources.
All sectors harvest resources.

In addition sectors may undergo transformations due to player actions.

Population Change

Sectors support a population. Each season, the population needs to eat, and may reproduce, this varies by sector. Some sectors have a limited population.

To feed the population in a sector, compute the amount of food needed. This is done by multiplying the population by the food requirements for that sector for the given season. Use the next highest integer to "round" this computation. If the global food count equals or exceeds the amount of food needed, deduct this from the global food count, and proceed to the population reproduction step.

If the amount of food needed is less than the global food count, set actual food to the global food count and set the global food count to be 0. Calculate surviving population by computing the percentage of people fed (actual food/food needed) and multiplying this by the population. This computation is rounded down.

After the population has been fed it reproduces. In some sectors this is limited by season or other conditions. If the population can reproduce, multiply the population by the growth rate and round down. Add this number to the population.

In some sectors the total population is limited. If the population exceeds the population limit for a sector, set the population to be the population limit.

All computations, including population change occur from top to bottom, left to right. Update the cell at row 0, column 0, then the cell at row 0, column 1, ...

Example 1:

The global food count is 200.

It is in the winter in a forest sector with  a population of 182. 
Since it is winter, the forest  consumes .7 food per person. 
This is calculated to be:

   182 * .7 = 127.4  or 128.

The global food count is adequate, so the entire population survives 
and the global food count becomes :

   200-128  = 72

In the winter a forest reproduces at a rate of 30%.  The new population
becomes:

   Population change:  182 * .3 = 54.6 or 54
   New Population:  182 + 54 = 236.

A forest only supports 200 people.  The new population is 200.

Example 2

Continuing with the previous example in a prairie sector in the winter.  
The population is 302.

The global food count is now 72.

The food required in the winter is .6 per person or 

   302 * .6 = 181.2  or 182.

Since the global food count is below this, the actual food is set to 72.
The percentage fed is:
 
    72/182 = 39.56%

The new population is:
    302 * .3956 = 119.4 or 119

Strangely there is not a restriction on reproduction due to starvation, so
the population in this sector reproduces by 10%.

    119 * .1 = 11.9 or 11

The new population is 130

Goods Production

Sectors support production. Production is accomplished in buildings constructed in the sector. Building produce items based on the building type, population and the order in which the building was constructed. In some sectors production is limited by season.

Production starts with the most recently constructed building in a sector and continues until the workforce is exhausted or all buildings have performed production. Buildings produce only if global resources are available. However, the workforce is used regardless of resource availability.

Sector bonus or penalty production is applied during production calculation (not to the units produced).

Example

A forest with a population of 30 has a sawmill (the oldest building) and 
a mint (the newest building).

The mint is the newest building so 20 workers will be used. 
If there are 7 gold available, one coin will be produced.  Otherwise the
workers will happily sit in the building and do noting.

After the workers have been assigned to the mint, there are 10 workers 
remaining, since the sawmill requires 14 workers to complete a task,
the sawmill is not open this season.  Those worker remain available
for another task.  

If there was an older building that only required 9 workers, they would be
assigned to this building.

Resource Harvesting

Once production is completed, the remaining population is free to harvest the natural resources in the sector. For each resource produced, multiply the usable workforce by the production rate to calculate units produced. Only whole units can be produced and production is always rounded down.

If a sector provides additional harvesting, this amount is calculated, rounded down and added to the normal production.

Example:

A Forest has a population of 30.  After production the usable workforce is 12.
The following resources are produced:
       Wood: 1.20 * 12 = 14.4 truncated to 14
       Food: 0.30 * 12 =  3.6 truncated to  3
       Gold: 0.10 * 12 =  1.2 truncated to  1

In addition, if it were fall, the forest would produce extra food based 
on the entire population.
       Food:  30 x .1 = 3
