I also wanted to clarity that I don't view any of this as a flaw in any way. The game is great in just about every aspect. Even the story is well done, it's just that it is one of those mind-screw type of plots, which I personally don't care for, and I know that I am not alone in this. It just really annoys me when some plots have you going through the motions & performing a lot of tasks, but ultimately to find out that it was all an illusion or just a mind-trip. That kind of stuff is insulting to me & really pisses me off. But that doesn't mean that I don't acknowledge that AW is still a very good game. I just don't agree with the plot, that's all.
Overall I thought the Signal was a good buffer representation that Wake was going insane trapped in the dark place. I'm hoping the next DLC builds on that and gives us more of the actual story verses just showing us that Alan is progressively getting more insane.
