Yes, so I think the main problem right now in game design is that it is stuck in the past. When games first came out in the late 70's early 80's, the graphics were very primitive. You couldn't tell complex stories, no voice acting, even the amount of text was limited. So the most basic type of game is like something like Space Invader where there are enemies and you can shoot them and move a primitive sprite around. Obviously the graphics weren't there to make a "walking simulator" like Gone Home, with a complex story and voice acting and text and photos and a realistic 3D house. That wasn't possible. So they made simple shooters, or sports games, or things that were possible with the technology. But now 40 almost 50 years later, the most popular games are shooters and sports games and these things that they made because of the limits of technology. And you do see innovative indie games come out still, but they are usually not super popular and sometimes no one has ever heard of them.
Like look at film. Film has evolved to the point where most things have been explored. Yes, there are new surprising movies and stories every year, and there continue to be evolution. But the technology is basically at it's peak (at least for a non-interactive 2D medium). The sets and make-up and special effects all look real. They can't really get any better, we're already there. But you see with movies there is so much more variety of stories. There are action, horror, and sci-fi, sure, but you have documentaries, education, romance, comedy, dramas, martial arts, biography, movies that don't even fit into a category. And there are mixes, like you can romantic comedy, historical documentaries but also theoretical stuff like about science or the future. There is just so much, and the stories are deeper and not the corny "DOOM GUY" stories they pass off as a plot in games, even in 2022. We're basically stuck in the past.
