I've just now played through this and I'm of two minds. Up until the last chapter, it was great. I think the strongest suit about this game is it's character development. Now, it's not perfect mind you, but it is very well done compared to a lot of other games. I genuinely was interested in most characters; Liam especially, he's fantastic and I empathize with his story.
Now....the last chapter. I understand the opinion of people not thinking it's realistic given the beginning situation with Megan. With how fast everything moved. But I see it as a fantasy situation grounded in reality. The situation is a fantasy itself in some cases, but it plays out somewhat realistically in terms of human reactions, etc. etc. But this last chapter is kinda "out there". I get it, there's psychotic stalkers out there but given everything else that's happened it's kind of weird in my opinion to tack on some crazy behind-the-scenes villain-esque character that's been there since the beginning. To me, it feels like a bad M. Night Shyamalan movie (from a decade ago, everything between The Village up to The Visit, that was a bad Shyamalan era haha) trying to make an interesting twist that....didn't actually add anything meaningful to the story.
I felt like, as the main character playing, everything that I worked towards in the various relationships was just kind of dashed in this chapter. One thing I hate in stories is the Amnesia plot device, where everything is basically restarted. Where the before didn't really even matter (unless that's the beginning of the story, then whatever). This isn't that, but it's close to that feeling. Everything's been flipped on it's head. The relationship between the character and, in my case I chose Megan, felt fragile. I'm not the story writer for this game, so I can't see into their mind. But as a player, it's really hard to see where this story goes that feels meaningful and doesn't hinder the progress made throughout the last few chapters.
Just my opinion, looking forward to see how this plays out.
