resources of anytype would drastically increase landvalue...
EDIT:
Here's how I think the land values/rules should work:
1. Any unclaimed territory (not within any borders) can be claimed by a citizen. The maximum amount allowed will be 10 tiles. These can't be sold, or traded for money, until a city is placed within that radius. If another nation builds in that tile, then that owner can either:
a. Claim for a "Rain Check" (10 new tiles)
b. Urge the military to conquer it.
2. Any claimed territory (within our borders), but not within a city radius can be bought/sold for 1/2 the price.
3. Any territory within the city radius is at the base price.
4. These are what effect the value of that territory:
a. No improvements: Base Value
b. Road: Add the value of trade (i.e., +1 gpt)
c. mines/irragation: Add 1 gold per turn.
d. rails: add 2 gold per turn.
e. Pollution: The value drops to 1/2 the territory value until the pollution is cleared.
f. Enemy unit: No value is gained.
g. Territory is marked as developed (houses): add 1 gpt.
h: corruption: the greater the corruption, the less the value (to be determined)
5. Buying and Selling - Citizens can buy/sell territory at the total value. The value is calculated using the above rule.
