+3 was my first computer, second was a500.
there were no original games on 3" diskettes in my country. so I played only those few that came with +3.
after some time (years) I figured out how to connect a tape recorder and play all those 48K games..
also there were always problem with sound and picture because of poor RF out (and different PAL system). wish I knew about RGB SCART then, and composite hack..
if the zx game is really good (and there are many of them), after some time you forget about its graphics limitations.

spectaculator is very good, I think.
basically all modern zx emulators are very good, best ones can do advanced stuff like microdrive and fdd emulation..
