Yeah, you pretty much need a walkthrough on certain path. Mainly the Ellie and the Dylan path . For Sam, it’s easy just choose yes for every interactions with him. But for Ellie for example, to have her kiss Sophia in the shower, you need to say fuck off to the street punks. How does that work ? Well after that, they assault Sophia in the subway, you talk to Patricia, you go with her to take revenge, which give you enough point with her to french-kiss her in the night club. Resulting in Sophia and Ellie french-kissing in the shower. But how can you predict that not responding to some thugs would block some scene with Ellie ? Especially when it’s separated by multiple updates. As for the harem route, I don’t understand what people are talking about ( unless they speak about the last update where you have to choose between Ellie and Allyssa) . In my playthrough, Sophia is going all the way with every major characters. And I’m not missing anything (until the last update) . My Sophia is doing as much with Ellie or Dylan as someone who would play her just for Dylan or lesbian or incest, or Ellie. Just accept every filthy, lesbian point and never say no and you shouldn’t have much problem.
