I have more of a problem with ugly "scanned" dithering. Take BASS for example. Nice art but the dithering really sticks out. Not that this particularly suffers from it.
This is an intriguing comment, as I always felt the "dirty" dithering quite made the essential "look" and "style" of BASS, adding in that little extra sense of decomposition, wear & tear. I feel the graphics retained, in this manner, something essential about the original Gibson backgrounds that more retouching might not have translated.
I do see what you mean, though, and I must admit I never really looked at BASS from this point of view.
