Altogether I'd say about ~20 Earthlikes and 10+ Water worlds. I've been bad at keeping my eye on if they are terraformable or not. :S
Wow! That's very impressive, to say the least!
See, those are very big numbers!...just wanted to make sure the difference was clear as for me, it took me a while -like a month or two- to differentiate Earth Like Planets, from Water Worlds, from Terraformable....I thought they were more or less interchangeable and more or less the same lot...they are not!
Yes, you have Water Worlds, but not all of those are terraformable...so, you have Water Worlds Terraformable Candidates as well and those are more like Earth, but still not Earth Like Planets which are unique.
Same goes with Gas Giants with Ammonia Based Life...and Ammonia Worlds....two different beasts...very simmilar but one pays off greatly -the Ammonia World, +20,000cr- and the other is almost as a regular Giant -1,600cr.
In the myriad of planets, the ones that are more rare and hence pay more, goes like this, from top to less:
Earth Like Planet
Ammonia World
Water World Terraformable
Water Worlds
Metal Rich Terraformable Candidates
