Story AND gameplay

I would say gameplay, because I believe that Haze had a good storyline and concept, but the gameplay sucked IMO

Usually also targeted toward teenagers. Very few RPGs have a good enough story to spark your average adult's interest.

Gameplay, of course. I don't care if the game has no story (SMG), but if the gameplay's great, then I'm sold. However, I would still buy a game if its story seemed very compelling, thankfully most of those games seem to have good game mechanics to go along with the story.

GAMEplay because its a GAME not a book!

Well as i have gotten older and less time to play video games I have gotten very selective. So while gameplay is important, if it doesn't have a great story then I will not waste my time. I love movies and books and prefer games that have a deep story. I am surprised that this is so far tilted toward gameplay! Obviously if the game play stinks then I won't play it, however I think that most games that have a good story are because they are from developers who are really trying to put out a great game and know what they are doing. Therefore most games with great story INCLUDE great gameplay. When the story is bad its usually because there have been so many problems with development (too human) or just poor game design. Thats my 2 cents.

A lot of WRPGs have very mature stories and there are even a few JRPGs that have mature storytelling i.e. Shin Megami Tensei series, Lost Odyssey

I will always choose gameplay over story. Of course, having both is nice.

I'm a fps gamer myself so gameplay.

Gameplay first story second.

I mean a good story but horrible gameplay? = me not finish game

Good gameplay but horrible story? = I can still enjoy it and love it ( Super Mario Galaxy anyone?)
