So, I've been thinking, if one would want to make a super-cross-platform graphical game targeted at somewhat common platforms, starting from #8bit, what would be the common denominator for the art?
The answer would probably be 160x128x1bpp as a baseline. Small enough to be displayed on #GameBoy, crisp enough for #ZXSpectrum, pretty enough for #GameBoyAdvance.
