If gameplay is important because it is in the name then graphics is the single most important part because vídeo comes first.
If gameplay is the most important because it differentiate it from movies and other visual arts Then graphics is the most important because it differentiate vg from other games we play.
There isn't a single most important aspect. If graphics wasn't important as well it wouldn't be the most requested evolution every gen followed by new mechanics/gameplay, etc.
The way people want to define gameplay more important because you can't play without it then I could say the single most important element of a vg is eletricity, as you can't play any without it.
