Source is Campaign Operations, corrected 3rd printing, page 123, Planetary Population Table
It is in Solar System Generation -> COLONY CREATION -> Step 1: Population -> Population -> Planetary Population Table, bottom half
In the Planetary Population Table, the bottom half is the Planet Condition, with a modifier for the various conditions.
The line for "Gravity 1.5-2Gs" has a modifier of "x.05".
However, the line for "Gravity 1.2-1.5Gs or below 0.8Gs" has a modifier of "x0.8", meaning that the gravity above 1.5Gs is 16* harder to live on than a planet with only 1.2Gs gravity (0.8 / .05 = 16).
There is also the line for "Uninhabitable", which also has a modifier of 0.05, and is for Gravity above 2 Gs. This is the same multiplier as for gravity above 1.5 Gs, which seems strange to me.
The gravity 1.5-2Gs modifier is also the only one that has a decimal as the leading character, rather than a leading zero.
I have taken the liberty of copying the table and pasting it below, with only the relevant 4 lines kept (title, gravity over 2Gs, gravity 1.2-1.5Gs, and gravity 1.5-2Gs):
Planet Condition | Modifier | Modifier Description |
Uninhabitable | x0.05 | Planet has a toxic, very high, vacuum, and/or trace atmosphere; gravity is over 2Gs |
Gravity 1.2-1.5Gs or below 0.8Gs | x0.8 | - |
Gravity 1.5-2Gs | x.05 | - |
My question:
Should the Planet Condition Modifier for gravity of 1.5-2Gs have a modifier of x0.5 instead of x.05?
It would make the multiplier have the same format as the other multipliers (a leading zero), and would make a planet with 2Gs only 1.6 times harder to colonize than a 1.2G planet rather than 16* harder to colonize as currently written.
