Graphics just like Audio, pacing, directing, level design, controls, etc are just one piece of the puzzle of what makes up a game. Without graphics there is no game - period. But sometimes they aren't as important as they are in other games. The Last of Us required beautiful realistic graphics to convey the story and characters, Minecraft has no need for these things.
Also "Good" graphics and "Realistic" graphics are not the same thing. For instance Fat Princess had great graphics, and so did Killzone 2 - just in different ways.
