Are you referring to Earthion specifically or just making some grandiose comment about pixel art in the good old days?

What are "CRT bloom and blending"? Are you referring to artifacts caused by composite video output? That is not due to the CRT but rather the signal distortion. RGB output on a CRT will look pixel perfect and colors will not merge. I'd say most gamers using original hardware on CRTs these days are using RGB, so if anything, it reflects the current user trends if the Earthion designer did not use dithering (which he did, making this comment irrelevant).
