Horace, then let's start or find a Speccy thread here!
NLS, nothing was gorgeous about the graphics of the ZX Spectrum, the best version of the Spectrum.
Nor were the graphics amazing for similar games for the MSX, SG-1000, ColecoVision, BBC Acorn Electron, etc.
But the grphics to me were charming and very simple. Focus on crisp, lively, very addictive gameplay.
