Yes with the correct choice, you can collect the main girls as your harem excluding the one that's not yet released. I've started a new game about 5 times now. I'll learn something new and starting over. I recruited all of the main girls and is able to have H-scenes with them. I have two separate base: one for the main girls and one with only natives. I collect a few natives and have children with them to populate my base. The trees and the stone aren't going to farm themselves. But for the life of me, I can't get them to auto-plant seeds on the farm. Not sure if it's even possible (yet) at this point.
