I'm not super into CoD and the last one I played (not counting remasters) were Advanced Warfare campaign and some Black Ops 3 multiplayer. They were okay but at that point I was quite tired with the series. I started BO6 on my XSX and the single player campaign is quite fun. I probably won’t be touching multiplayer on the account of being old.

The thing about CoD campaigns is that you have to suspend your disbelief and go with the flow of what game is throwing at you. There's a lot of scripted scenes where you just have to push through to progress to next scripted scene. If you play to exploit that you won’t get much enjoyment. Treat it like a amusement park ride and it’ll treat you with bombastic set pieces.

I’m not sure if I’m missing anything lore-wise. Black Ops 1&2 which I played were heavy on spy / CIA stuff, plot twists and I enjoyed them a lot. So far I’m just assuming BO6 is cryptic on purpose like older ones so it doesn’t bother me that I jumped without playing previous ones.

Technically CoD games have always been rather accomplished with nice visuals while targeting 60fps (but not making a big deal out of dropping to 50 or so). BO6 looks very good.

Overall it’s not some revolutionary or overly ambitious game but it’s quite competent equivalent of a popcorn flick.
