This is the article I read recently. But the wording/translation kind of confused me. My thought was that they had four complex romantic companions.
"One of the things that we actually have pushed in Starfield - so we have a number of companions, but four them, we go, I won't say super complex romantic, but more complex relationships than we've had in terms of not just whether they like you or they don't like you. They can be in love with you and dislike something you did and be pissed at you temporarily and then come back to loving you. In a lot of games, you just work your way up, they like you more and more and more and more, and now you're in a relationship. When you make him upset, you drift out of it like it never happened, whereas we wanted one where okay, we can be in a relationship and we've committed to each other in some way, but I just did something that really made you angry. As opposed to just drifting out of that status, you're in a temporary 'I don't like what you did' state."
