Industry is still fairly new, and it's changing constantly. So gamers will follow and accept those changes, innovations or trends or... not...
I think that after the PS2 gen, which was probably the last gen where japanese developers were at its ultimate top peak both in quality and performance; and was the generation that saw the arcades die; while still a lot of japanese productions (way before PS2 gen) had cinematics or some sort of movie-like inspiration... The focus was always gameplay, in one way or another.
But with Ps3-360 gen and western developers taking the lead, cinematics and storylines became a lot more relevant. The chase for the blockbuster movie-inspired-feel like game, or storylines trying to mimick popular tv shows, became a norm.
It's a different approach from the japanese style, and sometimes works even better, but some other times it just doesn't feel like a videogame.
Anyways, there's a lot of variety now. I understand that many (me included) can feel overwhelmed by bloated open worlds with a pointless pretentious storyline that goes nowhere, or just can't get into the supposedly complex storyline of some triple A single player by Sony studios because if it still feels like a forced and failed effort of trying to mimick a tv-show or movie, while in between throwing you some gameplay or slow walking sections.
But they are just a part of what the industry offers now.
Let's say there's more than just gamers now and all the trending new and upcoming genres have their place.
It's not like in the 90s that we all nerds like me just played countless japanese platformers, arcade fighters from Capcom or SNK and from time to time tried out some long ass jpanese rpg on Ps1 or Saturn.
