The Fallout franchise perform well... exept the last one... but because of the online matter ( Fo 76 ).
Fo 3 and 4 maked pretty good seeling despite old fans ( fo 1 and 2 ) shoot loud and with anger about "bethesda betrayal" since they have changed the game mechanics.
So last opus difficulties are not tied to the same reasons. It not because of the contrast with old ( classical ) games.
I see it this way. Their constant fiddling with the formula has finally caught up with them. It's not just the "online matter" but the fact that the story and writing the games are known for have been completely eschewed in the latest installment. There's no doubt 3 and 4 have sold well although I don't know how many copies they needed to sell in order to break even. My guess is a lot as production value must have been very high which leads me to believe that's why they tried changing up the base mechanics again with 76.
