Yup that's a fine idea and one which i've employed before now.
BUT
This means you now miss out on half the game which initially at least is enjoyable..
Fallout 4 could have been two games and probably should have been with one of the main stories being a DLC (a free one at that). Some of the quests are plain ridiculous too and it feels like padding of the worst kind, no substance.
Bit of bummer really to say how long we waited for the damn thing..
These are of course my own opinions whether right or wrong..
