I think its all equally important, but if I had to choose one part. I would say that gameplay is the most important.    

I find more and more of a need for a good story.  Of course if the gameplay is good I can forgive the simplicity or flaws of one's story.  Conversely if the story is great and the characters interesting I can forgive the lapses of gameplay.  Atmosphere kinda ties into that.

I have to go with story.  If I am really interested in the story i'll play for hours and i'll beat the game multiple times.  

Why can't I vote?

Gameplay is certainly most important. I'll put up with a game with no story, terrible graphics, and music that makes your ears bleed if it has great gameplay.

graphics AND story

Story, the game has to have a good story. Then game play.

I know for me it story. I've never been able to play Assassin's Creed because of its silly story.

I think a good mixture of everything, mainly Gameplay, story, and atmosphere for me, one of the reasons I loved Bioshock, it's gameplay and story were relally great, but what sold me most was the atmosphere I really believed I was there. :)

Gameplay, Graphics, Story, Atmosphere, Music. Examples of great uses in this order :Deadspace(s) Bioshock(s) Fallout(s).

A good mix of everything is definitely important. Everything falls flat if one part is fantastic, but the rest sucks.

Story ,story , story. I could deal with crap graphics and passable game play. But i can make a connection with the characters and want to see how there story ends then the game is worthless. I love the God of War games. In fairness all the game are pretty much the same game-play wise but what hold me is the story and how as bad kratos is ,he is still a man that can be redeemed

Story

Gameplay and story are definitely on the top of my list, but gameplay edges out story just a bit
