There's gonna be scenes with the human girls.I think the idea of only green is cool but from the player's point of view it is a waste not to have scenes with the other girls, perhaps he lacks a side character to accompany him on the adventure, it could be son of a human couple from the past who negligently had an absent father, the classic mother died of an illness and now the father must take charge, so we would have the opportunity to play with both of them, have two visions, even have different missions and with time to have scenes with the humans and the goblins without losing anything and without having NTR.
I'm finishing up the new main quest atm (part 1 is already out), and then it's back to town and the 'human relations' plotline will kick-off.
