Immense. I'm one of the ones who wants the biggest map possible.
So why don't you set it to abundant?
I never play with abundant habitable planets on any game. It increases the amount of micro-managing to an intolerable level, and in addition, there's a lot of evidence suggesting the AI does better with less planets. This thread isn't really a complaint about the game, but is about whether I'm remembering correctly that TOA is supposed to have more planets on average.
Edit: Apparently I was just a victim of bad luck. I looked at the debug.err file and saw:
Debug Message: Star Frequency: 4 Max Num Stars: 320
Debug Message: Planet Frequency: 3 Max Num Planets: 1024
Debug Message: Galaxy Size Set: 22 x 22

Debug Message: Total planets placed: 65
Not sure what the "failed to place planet" means, but it looks like I just got about as small a number of planets as possible.
Second edit: Ignore the above... it looks like it says "Total planets placed: 65" no matter what the settings are. Not sure what it actually means but it certainly isn't listing the number of planets.
