The launch trailer for Fallout 4 came out about fifteen minutes ago and goes a bit into the plot, which I want to talk about.
It seems as though the story will revolve around the Institute and Synths, along with paranoia about the two. I feel as though the plot points predicted as far back as when rumors were surfacing about location scouts in Boston are all being confirmed. I think the "plot twist" will almost certainly be that the protagonist is a synth and that is why they haven't aged a day despite it being two hundred years later.
The player at some point really urgently needs to find the Institute. I feel as though that's going to be because of some sort of maintenance or repair that they can offer you and you desperately need.
Now I want to hear from you guys. Thoughts? Counterpoints? What are the Brotherhood of Steel and the Supermutants up to?
