Under DL, obviously all the unowned planets that usable squares could be
inhabited. Normally I would have them sorted based on the number of squares
available.
Under DA, when you do this listing, it lists all of the unowned planets but obviously
you can't inhabit most of them unless you have the techs. Some don't need techs.
The only way to find out from this list is to click on them and then you find out
whether they need aquatic, radioactive, etc. tech.
Is there some way to list all of the unowned planets that can be currently colonized?
I know the main screen shows what kind of planet they are and the color of the special planet icon changes if you have the tech. Maybe the list of unowned planet could show this icon too.
