In my opinion I think the cut scene from Origins is a framework which the story has followed since the beginning of the Zombies franchise. I think the maps we've played and challenges we have completed have been a microcosm, or a look to what is going to happen in the future. Through the imagination of Samantha and Eddie we have already seen the events as they have unfolded. I think the story we've been told so far is legitimate but has yet to come to fruition. I think Samantha and Eddie finishing their game when the sirens begin, signifies the beginning of the actual events as they will happen. During the cut scene we see bottles of Juggernog, zombie figurines from Mob of the Dead and Buried, a giant robot is in the back left hand corner, there is a box full of toys with a "?" on it. I think these elements which Samantha and Eddie had around them as kids had an influence on them as they replicated the events in real life.
However, I do not know:
A) Will Eddie grow up to become Edward Richthofen. Hypothetically, if the story is not fictional I think it is possible. Maxis and Richthofen have a significant gap between their age when shown during the beginning cut scene. Secondly, during Origins while playing as Richthofen the character makes regards about Samantha which seem like they have a history together.
Is the house in the cut scene a place you can visit while playing Origins,
C) Will this house be in a future game, there was an MP40 chalk drawing on the wall which leads me to believe we will be able to play it in the future.
These are my thoughts I want to hear what you guys have to say!
