This reminds me of a topic on the first game's board a while back that had long encyclopedia-like explanations of basically every single thing that could possibly have potentially been referenced to in the game. I'm reminded of how English teachers like to delve into every single thing they think is "symbolic" even though there's no way of knowing if that "symbolism" was actually present and intentional or if they're simply trying too hard to find some hidden depth.
So what, they just threw the secrets in there for kicks and giggles? There is definitely hidden depth. If you just don't want to look everything up, I respect that. Just don't knock on the story too much when you don't know the whole thing.
