Yeah, marketers doing their usual thing lol.

These days, I often can't tell if cutscenes are pre-rendered or rendered by the game engine (or another real-time renderer packaged with the game).

Though that some of the old Blizzard cutscenes that impressed me a lot at the time stopped being so impressive even a decade ago. Like the Diablo 2 ones are on the far side of the uncanny valley still, but I remember being awestruck by them back in the day.
