Too bad the funny fact is that the only reason that's happen is not because it outsold Battlefield 1 by a lot or whatever, is just because Titanfall 2 bombed hard...

Didn't you predicted COD Infinite Warfare to outsell Battlefield 1 by over double in another thread?

"Call A Doctor rather"

Well I suppose it is time. CoD has had yearly releases about the same amount of time since WoW released. Both of these games had massive declines after 7 years, but the difference is Blizzard is still at least trying to sustain their player base with good/bad innovations.

And with it,  it sold more at a higher price.  Activision will definitely remaster another cod with the next one.  Probably WAW. 

Call of Duty is a decent game that sells amazing numbers each and every time. In some cases, Battlefield was ahead in terms of being a good game, like 3 for example.
But not always, Hardline was terrible. It seems that Battlefield 1 is a masterpiece in many aspects, but CoD will always sell well.
It is like the Transformers movies. We can bitch all we want about how they have no soul or substance, people like them.
And, in CoD case, the multiplayer is just a lot of fun, it is fgreat value. I can put CoD Ghosts today in my Xbox One and have some chuckles playing for 10 minutes, it is a good thing.
That said, no CoD game should never ever win Game of the Year. But I totally get why it sells.
