The web is already a game runtime that works on Linux, macOS, Windows, Android, and iOS* with decent graphics. I've ported a couple of games. Here's Quake 3 including multiplayer https://thelongestyard.link/ and Cave Story https://thelongestyard.link/cave-story/. There are full-fledged web-native games too such as https://gooberdash.winterpixel.io/ (2D Fall Guys) and https://krunker.io/ or https://venge.io/ (multiplayer FPS). And of course one of the most popular recent games has a web version: https://poncle.itch.io/vampire-survivors

* Even more platforms: Chrome OS, Meta Quest, Tesla cars, Xbox, smart fridges, etc. The web is unmatched in platform support and more importantly allows you to completely bypass the software distribution monopolies on all of them. Ship freely without anyone's permission!
