With CoD it was ultimately just oversaturation. The exact turning point was 2011, which is also where its general popularity peaked (though obviously still very high selling). Modern Warfare 3 was when the discourse around that franchise started to sour and reviews started to get worse. Black Ops 1 from 2010 is actually still the highest selling CoD game (as far as we know) despite MW3 launching bigger, which imo is kind of a sign that thats where the fatigue started. Of course even with that fatigue its still big but it is there.

If CoD had been once or twice a generation and kept up the quality of CoD4 through Black Ops, it would likely still be strong on here.
