I recommend a RESOURCES indicator.
It would be in indication of the natural resources of the world/system. It would represent both the PHYSICAL resources (metals, gems, radioactives, etc) and the BIOLOGICAL resources (oil, wood, pharmacuticals, food).
I classify each of the 2 types of resources into 4 categories:
LOW: Enough to support a population of 3-
MEDIUM: Enough to support a population of 4-6
HIGH: Enough to support a population of 7-9
RICH: Enough to support a population of A.
If the world's population is higher than the resource number will allow, then that resource must be imported. Higher resource numbers allow future growth of the population.
Stable, self-sufficient worlds cannot have a population that is higher than what BOTH of the resources can support.
Each of the resource types is rolled on 1D6, so that 1D66 can be used to create the Resource Roll.
1D Resource Range:
1 Poor
2 Medium
3 Medium
4 High
5 High
6 Rich
Here is how the table will look, Bio across the top and Natural down the left side:

LOW MEDIUM HIGH RICH
Low 0 2 5 A
Med 1 3 7 C
High 4 6 8 E
Rich 9 B D F
</pre>[/QUOTE]Coding it back to the D66 gives the following:
</font><blockquote>code:</font><hr /><pre style="font-size:x-small; font-family: monospace;">
1 2 3 4 5 6
1 0 2 2 5 5 A
2 1 3 3 7 7 C
3 1 3 3 7 7 C
4 4 6 6 8 8 E
5 4 6 6 8 8 E
6 9 B B D D F</pre>[/QUOTE]While at first, the table is a bit counter-intuitive, it gives you 2 pieces of data in a single number.
I would have DMs on each of the D6 based on the physical characteristics of the world.
My first run at them would be as follows:
BIOLOGICAL:
-3 if ATM not 4-9
+1 if ATM 6 or 8
NATURAL:
+1 if SIZ 4- (why else would people go there?)
Others could be possible.
WADAYA THINK?
The D66 idea to represent 2 parts of a similar thing could be extended to others... I am working on a similar D66 thing for a general planetary system arrangement...
Other IDEAS?
