No one's pointing a gun to their heads to use MOCAP or photorealism.
Well, investors are pointing. The curve on the graph should move not only to the right but also upward.
The thing is, video games have long since ceased to be a niche, controversial hobby for geeks. Now it’s a socially acceptable and trendy hobby for "normies". And their preferences are as predictable as can be. The marketing industry exists for a reason :)
About 25 years ago, people in the gamedev industry were already saying that making games for the "core audience" (nerds and geeks) wasn’t profitable. It’s profitable to make games for the "average Joe". He has very little idea of what he likes (or doesn't know at all), which is exactly why it's very easy to make a choice for him.
A similar situation has long been observed in the field of photography. While in the 90s (the film era) everyone knew that if you wanted "interesting" photos, you had to lead an "interesting" life, by the 00-10s the focus had shifted to the need to own the most expensive/high-tech (and with as many megapixels as possible) camera. I don’t know how this affects the "interest" of the resulting photos, but that’s the direction the industry has taken. Because the average
Joe camera owner never takes it out of the house, he never goes anywhere, he has no imagination, let alone an interesting life. So, since he therefore doesn’t have any “interesting photos”, you have to sell him
something he understands. Nice numbers on the package box, for example. Everyone knows that 3 is greater than 2, for example. So therefore 3 is better right? And that’s why today it’s easier to sell megapixels (= mocap/photorealism) than attractive straight out of camera colors (= gameplay). Every “modern photographer” knows that the more megapixels, the better the camera (and the photos). And good color is some kind of meaningless nonsense so don’t go acting all fancy here, just buy a set of Lightroom presets for 100-999 bucks.
As a result, cameras are becoming even more technologically advanced (and more expensive), but there are still no “interesting” photos in the average Joe photobook. Just as there never were.
