So I played this a while back but I wanted to come back and check if there's been any updates/new info. There hasn't, but I played it again anyway because I do love it.
So spoilers, but
I'm so torn with the Call Scytha/Call Rohan's people choice. Because going with Scytha is one of the few ways that you can get IVI back right now, but also going with Rohan's people gives you the opportunity to build relationships more - I'm guessing that's the whole axis of that choice, tbh. And I know that the chance to get IVI back will come along later in the storyline anyway but with how I play the Operative (frankly just devastated by losing her, and willing to do anything short of murder/grevious bodily harm to get her back... that chance, it feels so important to get it.
