Well, what is uninhabitable gravity?
Over 1.5Gs, when a significant fraction of the population starts have regular heart trouble. Extra gravity isn't just carrying around more weight - one of the ways it manifests is higher blood pressure requirements to get blood to the brain.
Some of the planets my thing has generated I've seen up to 2.0 gravity. Using the real-world formulas for a planet's mass (75 - 125% of Earth) and a planet's diameter (75 - 125% of Earth) it will get up to 2.0 and usually no lower than 0.6 gravity that I have seen.
That's about what I was aiming for, something that would bracket and exceed canon, published gravity (0.5G for Riken Minor and 1.7G for Promised Land). And, yes, that range of gravities could generate worlds with reduced habitability. Just like it's hard to get habitable worlds around some types of stars.
So, proposed errata, feedback welcome:
LOCATION: p. 123, Planetary Population Table
THE ERROR: The planet condition modifier, "Gravity below 0.8G or above 1.2G" appears to overlap the "Uninhabitable Modifier," which includes "Gravity over 1.5Gs."
THE CORRECTION:
1) Delete "gravity is over 1.5Gs" from Uninhabitable row.
2) Change "Gravity below 0.8G or above 1.2G" to "Gravity below 0.8G or 1.2-1.5Gs"
3) Add row, "Gravity above 1.5Gs," with a modifier of x0.5.
What would space stations and asteroid fields (Star's End) count as "outposts" for the population table?
I'd count them as uninhabitable worlds rather than outposts. You could potentially have a large population (500 million x 4d6 x 0.05), like in the Slowboat Colony "Columbia," which is settled in an asteroid belt.
