I want to make a new race, but the races that would fit them best I don't want to replace, and the ones I do want to replace wouldn't work with them. So is there a way around this?
You can move the existing species over to the left and add two more on the right. That's what I did... although the screenshot was taken before I ended up moving all of them even further to the left.
Oh! Okay, now that I know this is possible, I'll have to look into this. Thank you for the confirmation!
