Editing Trinity:City Mechanics (section)

=Wealth, Resources, and Currency=
Rather than saying that a city of a certain population has a max GP limit of some number, the maximum GP limit of a city is determined based upon its abilities and classes. Wealth is determined by classes, which is then multiplied by population, to find the max GP limit of a single item that can be purchased in the city.

Resources, Economy, and Infrastructure each further impact currency. Instead, Resources modifies the value of 1 gold piece. If a city is at it's normal Resources value (Wealth x 5), gold pieces are exchanged at a 1:1 ratio.

* '''Resources:''' Modifies Max GP Limit for the city, as a percentage.
* '''Economy:''' Modifies the value of 1 GP, as a percentage.
* '''Infrastructure:''' Modifies item availability.

===Resources===
Resource fluctuation causes the maximum GP limit of an item that can be purchased in a city to go higher and lower. For every point above the normal Resources value, the max GP limit goes up by 1%; for every point below, the max GP limit goes down by 1%.

In addition, if a city's Resources drops to 0 or below, the max GP limit drops 5% in value for each point of Resources below 0.

===Economy===
Economy fluctuation causes the currency to gain and lose value. For every 5 points above the normal Economy value, currency gains 1% in value; for every 5 points below, currency loses 1% of its value.

In addition, if a city's Economy drops to 0 or below, the currency drops 1% in value for each point of Economy below 0.

To determine Economy's effect on the price of a given item, divide the item's price by the currency value as a percentage. This will result in the city's price for the item.

===Infrastructure===
Every standard item has an availability rating, on a scale of 1-100. Any item whose availability rating is equal to or below the city's Infrastructure can be purchased in the city at the city's price for the item (standard price modified by Economy).

If an item's value is below the max GP limit for the city, but its availability is higher than the city's Infrastructure, the item can still possibly be found, but at higher prices than normal. To do so, follow the following steps.

# Determine the Craft skill that would be able to produce the item. If the city has the skill, proceed to the next step.
# Multiply the city's skill bonus in the skill by 5.
# If the result is higher than or equal to the item's availability, the item can be found in the city.
# Subtract the city's Economy from the result in step (3). If the result is below 1, the item cannot be found in the city. If it is 1 or higher, subtract it (as a percentage) from the city's currency value.
# Divide the item's cost by the result in step (4) (as a percentage).
# The result in step (5) is the cost of the item in the city.

===An Example===
 Edge has a Wealth of 14 and Population 52, meaning that it's Max GP Limit is 728 GP. 
 
 However, Edge recently suffered an explosion in its industrial sector (+38 to Disaster), which resulted in a loss of 38 Content,
 Infrastructure, and Resources; a loss of 19 in Leadership and Economy; and a loss of 9 to all other attributes.
 
 '''Max Item GP:''' Resources is now 38 points lower, resulting in a 38% drop in Max GP. The new max GP Limit is 451.3 gp.
 
 '''Currency Value:''' Economy is 19 points lower, to a 16; this results in a 3% drop in currency value. To purchase an item of the
 max GP limit (451.3 gp), a person must spend 465.3 gp.
 
 '''Item Availability:''' Infrastructure took a 38 point hit; Edge's original Infrastructure was 35, and is now 16. Items with an
 item availability of 17 or higher are no longer available.
 
 Let's now say that a character wants to purchase breastplate in Edge (35 availability).
 
 Edge has the Craft (Blacksmith) skill, which is what is required to make breastplate. Breastplate's base GP value is 200 gp, lower
 than Edge's current max GP limit. So the item can possibly be found, but will be (even) more expensive than normal.
 
 Edge's Craft (Blacksmith) is +7, x 5 is 35. 35 is equal to or higher than the item's availability, so the item can be found.
 
 Edge's Economy is 16. 35 - 16 = 19, which is greater than 0, so the item can be found. This is subtracted from the currency
 value, resulting in currency's value being 22% of normal in regards to buying the breastplate.
 
 To purchase the breastplate, currency is treated as 78% of its normal value, meaning that one will need 256.4 gp to purchase the
 breastplate.
