I love the Retcon, I mean when you first 'die' at the end of Portal you end up in a street/entrance to aperture. What happened to all of it? Is this some sort of 'Side' entrance or a backdoor?
Also WHY DID THIS GAME MAKE ME SAD?! The game was very very very fun mind you but, after playing the ACT 2 portion and learning about Cave Johnson, Bring your Daughter to work day and how GLaDOS was forced into the robotic position, it just... seems sad. Also I have a very strong feeling that GLaDOS is Chell's mother. Adoptive mother mind you.
Don't forget Chell's fate.
While it's possible there are humans out there, it looks pretty overrun. If there were people, they would have found Aperture, and done something. GLaDOS might have let Chell go, but the poor girl is most likely facing a slow decent into madness and starvation, depending on how well she could survive in the wild.
As for GLaDOS... I've always thought she used to be human, to some degree, and it was rather bittersweet to get the near-confirmation. Worse still with some new thoughts- if it had been shown that using a human mind would work for something like her, why not do it again? The Cores, original and defective, could have well had human origins. Whether she is/was related to Chell or not, I can't say (I, personally, don't think that. It just doesn't manage to line up right. I figure the science experiment thing was more of an Easter Egg than any hard canon fact).
... so yeah, Portal 2 is a pretty damn depressing game ._.
