We need to not glaze it so much. It's cool that a rock put these demos together, but they're not "really fun". Not even close. The UI is pretty thanks to the Claude Design's injected stylesheet doing a lot of heavy lifting.
Also, it's been easy to make not "really fun" games since the late 90's with no-code game maker tools. Klik & Play anybody? GameMaker? The only difference is now, thanks to the hard work of Three.js and browser tech contributors—the graphics are better.
