I believe the reason why the graphics on the PC were so low res is
because they were merely ports of the Apple II games to start with.
Then, when they moved over to developing the titles on the PC, they
didn't change their engine technology because that resolution was the
most compatible with the C-64 and Apple II systems of the day.

The Apple II version of King's Quest was one of the early
double-resolution 16-color games and subsequent Sierra adventures used
that graphics mode.  Double-res on the Apple II was 160x192 with 16
colors.  Mixed-mode graphics on the C64 was 160x200 with 4 colors (from
a 16-color palette) per 4x8 character block.  It was just a logical
decision to use the same assets and resolution as the other popular
platforms.
