Derthrean: | Good (+28) |
Phinnert: | Adequate (+28) |
They're both Organic, so the specials apply equally. There wasn't anything listed for either about population bonus/deficit, other than the rapid colonization for Phinnert.
For swamp worlds you see a difference as expected, with Phinnert having better numbers.
Phinnert: | Good (+16) |
Derthrean: | Adequate (+12) |
The numbers don't give a breakdown of how the projection is comprised, unlike when they're actually colonized.
