It’s less the feels (though the glow from a CRT in a dark room is entirely different from an LED) and more that the games especially were designed for the bleed and flow that CRTs have.

It’s similar to how subpixel antialiasing really depends on the screen design and what order the colors are in.

The pixelated 8bit aesthetic is more reminiscent of early emulators in LCD than how it actually was “on hardware”.
