I'm glad graphics are plateauing, now it can all come down to the game or story or features instead of just a bullshit wow factor. Dedicating all the resources and power to graphics is too superficial. It's time we saw more investment in AI, unique game concepts, lowering dev for more indies, dynamic audio, VR, physics. simulation systems, quality control etc.
If you look at modern 1080p/4K 60fps and higher gaming these days and are disappointed by the visual quality alone you're part of the problem. Devs have processing and storage resources to spare these days, if they didn't push graphics so far they could optimise less for stable frame rates and focus more on quality content or concepts. It's a game development paradigm shift I highly welcome in fact.
I'll take more innovation with games like Sea of Thieves, Forza Horizon 4, Ratchet & Clank, Control, GTAIII & V, Mario 64, DOOM, Tetris OG & 99, Ori, Superhot, Max: The Curse of Brotherhood, Super Meat Boy, Fez, Rocket League, Metal Gear Solid, Guacamelee! 1 & 2, The Forest, Minecraft, Hades, Among Us, Cuphead, Destiny, Portal, Wii Sports, Tony Hawk’s Pro Skater 1 & 2, Pac Man, Space Invaders, Super Mario Bros, Goldeneye, C&C, Tie Fighter, Sim City. You generally don't go wow these games continue to have best graphics 10 years later. It's the innovation, creativity and gameplay or interactions that keep these games as hall of fame classics and top shelf experiences to be shared for generations to come.
