Now, I know, graphics don't make up a game.
But they DO make the game more fun on some levels.
You see, graphics add to the atmosphere. They give you something to look at, eye candy basically. You see, here's an example, GTA IV. Everything is brown and stuff, and it's all depressing. This decreases the fun of the game, making it more boring to look at and such (atleast for me, cause I play on a console and there's nothing much to do here). Saints Row 2, however, has a more "happy" look to the game, even if that graphics aren't all that great. You see, the contrast and the shade of the colors makes it seem more fun. This is just my view, however. Discuss.
