If you haven't seen it yet Fallout 4 has a trailer and is now officially a thing. Needless to say I am excited....Fallout 3 remains my favorite game and experience as PC gaming goes. Consider me officially pumped. Enjoy a view from Dogmeat's perspective.
It apparently takes place in post-nuclear Boston, but I haven't heard where along the Fallout timeline they plan to set it. The last two games took place close to 200 years after the war...sort of hoping this one takes place a bit sooner in the continuity, when things are still more wrecked and disorganized than they are later on.
