I've pre ordered the last few CODs digitally, full edition (with season pass), and really enjoyed all of them. I am neither hyped nor disinterested about this game, its just the annual COD - I'll buy it digitally on PS4, hope its decent, I'll play it, lose interest after a while, and stop playing after 4-6 months. I don't expect anything really that innovative or that new or different, but playing with a few friends on weekends is worth the $60-90. The only big question really is whether they will include a remaster of something like MW did with IW.
I only recently actually started the IW campaign, by comparison my character is nearing level 47 in multiplayer (usually 2-3 games a week; I hit prestige level 3 or 4 in BO3 so I played that a LOT more). I am absolutely loving the SP campaign in IW, it feels very much like a mashup of The Expanse and a prequel to Mass Effect.
I bought all 3 games at launch - BF1 and Titanfall 2 on PC, IW on PS4 - and what shocked me the most was Titanfall 2 is the game out of the 3 that has captured most of my play time. I really enjoy that game (1 game a day) whereas I've barely touched BF1, even though I really enjoyed it the first week I just find something about T2 very fun and fast.
