What in your opinion, makes a game good?

What makes a game great? The music? Character design? The type of game it is? Or is it a combination of these things that make a game great?

In my opinion, you need a good combo of these characteristics. A game with good music, is interesting, but stupid and dull. Though some people will play any game no matter what the music, character design, etc. is as long as its First Person shooter or whatever.
