Saying stories aren't evolving is incorrect. Let's take The Last of Us 2 for instance (not my favorite story outcome, but still, just to make a point). They use new graphics technology to show bruises and body marks and display so much emotions in the characters eyes and face that you don't have to guess what state the character is in, be it either joy, rage or sorrow.
So a good graphical game that pushes the graphical advances as a tool to enhance the story creates these "benchmark games"..And you need in turn other tools to make this happen as well, like motion capture, directors - screen writers who knows what they're doing. That stuff is super expensive - but the outcome, if the story is good enough - creates something wonderful.
Not all games have to be like that of course, great games can be made with fairly simple graphics - Nintendo has shown that over and over..But I wouldn't want that as my only option on the market. Some times I want my heart ripped out by characters I feel emotionally attached to
I think that using the graphical merits of a game to show that the story is important is a very strange approach.The fact that good graphics can enhance the story is certainly true, but I don't think that the formula of "good graphics + good story" is particularly valuable and says anything. It's the same as saying just “make a good game and everyone will be happy”. Improving the graphics itself improves the perception of other aspects of the game.
Besides, the Last of Us series, although focused on graphics and story, it's debatable that the story is decent (this applies to both games, not just 2). I would say that graphics and attention to detail is more characteristic of these games, you can have fun purely because of immersive combat and realistic gore, even if you are not interested in the story at all. Take that away, and no matter how awesome the story is, the game loses all sense of playing it.
Also, the sales of the series are not that big, considering the unique experience that it offers and the prestige of the developers. Such games in any case will lose in popularity even to completely mediocre products like pawlord and their sales will be inferior in times.
I'm certainly not saying that story is unimportant per se, I'm just saying that we shouldn't pretend that gamers care about it so much. The gamer community has never been as disconnected from reality and adequacy as it is now, and there's little to say about what they want other than to focus on the popularity of a certain game and draw conclusions.
Also, you have to be more careful in assuming that a particular game will be successful simply by virtue of this and that. There are a number of cases when worthy and great games received much less attention than they deserved and vice versa mediocre products received a hype train beyond measure.
And as for the expensiveness of AAA projects, it's a sacrifice that has to be made, otherwise the whole gamedev will turn into an amalgam of battle royal and other greatest multiplayer masterpieces.
The fact that AAA developers have not yet crossed this rubicon, says that they deserve respect, although reading this kind of articles gives the impression that gamers are begging them to do it, because they are so tired of big games.
