Romance is completely worthless if you choose the dialogue of more than one protagonist. For the sake of immersion(not feeling like I'm playing the game by myself but with a companion that may disagree or agree with some of my choices on their own), the game should have an option to make one of the protagonist AI controlled. I don't know what they were thinking. Majority of people aren't going to play co-op.
The game DOES have an option to make a protagonist AI controlled, for now there's the random option but at launch there will be more options to designate a character type to a protagonist that the AI will play out so what are you blabbering on about?
