Nice Op, there are different things to say in that case.
_I think the innovation cult is something particular to the videogame industry, and it's kinda absurd compared to other forms of art. Cause we don't ask a "genre" movie to reinvent the genre, even if it's nice that some does after a time. But nobody judges a movie or a song by thinking "so what new things does it bring ??". cause well even a classical horror movie will bring its tone, story, aesthetic.
And in the order case, it's clearly bringing a tone, a pace, a setting, an aesthetic, and probably a pretty rich story for a game of that genre. BUT people act like a videogame is a material product, like if it was a software or a camera, and they consider it should be an evolution compared to other games, especially at the beginning of a gen.
Now, i'd temper my own words by saying in that case.. the genre in itself is kinda boring, to people, i guess, cause it's not even like Uncharted, a dynamic tps with climbing and amazing action scenes. They show something really slow and limited in what you do, so i can understand why people are not super excited.
Also i'll re-say it again, there is a problem with Sony first parties. They are kinda blind and self driven. KIll Zone, Infamous, Drive Club, Knack, The order all lacks some ambition in their gameplay, and all have a pretty arrogant way of being tech showcase, not even that efficient in all their aspects. It's like those teams are more driven by the tech challenge (they all have intensive reflexion/light techs, even Knack has the 3000 piece character thing) and are all into the big cinematic game style, while XBO exclusives have a more retro, simple fun kind of approach.
It's like people at Sony takes videogames a little too seriously sometimes and can be distant from gamers pleasures. I mean everything is relative, it's not like they are horrible games.
