I stopped buying them after MW3 as it started getting more futuristic & eventually jumped the shark. This one is getting me back on board.
Black Ops 2 was one of the best ones, in my opinion and the opinion of many others, but other than that you only missed one mediocre game (Black ops 3) and three seriously terrible games (Ghosts, Advanced Warfare, and Infinite Warfare).
I did not play a single minute of Infinite Warfare. I played all MWR last year just for the nostalgia
Since CoD4 I've always played a lot of CoD mutlplayer and even when I hated the other jetpack ones I toughed it out and played until max prestige... Infinite Warfare is the first one I've ever not finished. Just a horrible game.
Then MWR was good (CoD4 was tied for my favorite CoD with MW2, so I was crazy excited to hear they were remastering it) but I think they ****ed it up. Adding new camos is tolerable... adding new guns is stupid.
In my opinion, it goes CoD4+MW2>BO2>MW3+BO1>WAW>BO3>Ghosts>AW>IW
