If you haven't played this game yet, play it. Go in blind. Do not read any spoilers. Even if you have heard spoilers, play it anyway. It lives up to the hype.
I'm going to have to hold off before I post a full review. Giving an adequate analysis of this game is going to require some time and effort, especially since the game really requires some intertextuality to fully understand. I'm going to have to play a few more (related) games and watch some movies before I feel like I can really talk about this game and how it fits into its context. And no, this isn't some kind of weird troll--I genuinely think this game has a great storyline and it deserves to be explored in detail.
