Well, to be honest, a game with great gameplay elements is something I can only play for so long, and it's not going to grab my attention much. I can sit down and play Tetris for three hours straight because the gameplay is kind of fun, but if (when) I lose suddenly, I'm not going to have a problem with it, I'm just going to wander off and do something else.
On the other hand, a game with a good story draws me in and keeps me playing for more than just the "fun" of the gameplay. When I die in, say, Half-Life 2, it's a big thing. It's not about just losing a game, it's about a character--my own character--actually dying. When I die, I often will get upset (at myself, if I make a stupid mistake, or at the computer if something dumb killed me, like a headcrab) and instead of going "Meh, time to do something else now", I immediately try again. You invest a lot more in a game with a story than you do in one that does not, and this means that when you lose (or win!), the stakes and the feeling of loss/accomplishment is a lot higher.
Obviously, I think it's very important to have good gameplay as well as a good story; if you can't stand the gameplay, not even the best story ever can save a game. But I also think that unless the game is one specifically designed to have only minimal story (Tetris, Pac-Man, etc.), a poor story hurts the game, because it just can't draw you in. A game that tries to have a complete story but fails is even worse, because it becomes a series of puzzles (find key, open door; kill monsters and live; find objects for NPC, etc.) that the game tells you you should care about, but you don't.
