I disagree. Call of duty is an arcade game which uses the ww/mw thene for content. Spielberg may have attempted to bring some kind of realism via moh but the core arcade genre was already there and hasnt changed much.
I’m not totally sure where you’re disagreeing with this video. I don’t think he’s trying to claim that CoD singlehandedly invented the war shooter, just that its gargantuan popularity and the way it handles its themes and its feedback loops are at odds with the subject matter.
Fair point but shooters have always used subject matter as window dressing.
