Well, i know this topic is dead. And i know most of you may have already saw this. But im posting it anyways.
In the fallout 4 trailer it says "Fallout, Prepare for the future." at the bottom on the 'all rights reserved' thing (idk what its called.)
it also says this on Fallout 3 'all rights reserved' the messages are identical except for a few things, like the date, etc. Fallout New Vegas 'all rights reserved' message is different than both of these, leading me to think the 'Fallout 4' message is just a fallout 3 message with a few things changed.
Also, in *almost* every fallout trailer, there is tons of action. with the exception of a few, like the New Vegas one where *robot* (*sorry i dont remember what some of these things are, havent played fallout in a while.*)
is digging you up. But toe 'Fallout 4' Trailer is all quiet, and calm.
I havent played Fallout in a while, and dont know much about it, but i wanted to show those unaware of this.
