I guess you are telling about the radio music. Soundtrack is some of the few things Bethesda did right. Inon Zur made music even for Fallout tactics and 3, and they are good too. I too hate that BOS is spawning everywhere in fallout 3 and 4. For a 3d Fallout game, the engine is not that bad. I think it is actually good in NV. Though it is a bit too janky.
