Dark brotherhood is the best. Especially the one where you get locked in a house and have to kill the other guests one at a time.
A thing I just noticed, in all the fallout games up to 4, the bombs fell on the night of October 23rd, 2077. In fallout 4, they retconned the time they fall to be in the morning of October 23rd 2077. Probably to make the pre-war environment more visible to the player. The history of "the great war" on the wiki now uses the time referenced in fallout 4 as the official time.
