Depends on genre, but in general I would say gameplay is more important for gaming. Story is more important for reading, for watching dramas etc. Visuals are more important for AAA blockbusters, and very important for FPS games based on real world etc.
Talking about Bioshock, Alan Wake, The Last of Us, The Walking Dead etc, I'm for the story.
Talking about Super Mario Bros, Fallout New Vegas, Total Annihilation, Mortal Kombat etc, I'm for the gameplay.
Realistic graphics is awesome. Infamous Second Son, Forza Motorsport, Battlefield, NBA 2k etc looks fantastic, but anyway personally I prefer addictive gameplay and touching stories first.
The game with story only. The Walking Dead. I like it.
The game with pure gameplay. XCOM Enemy Unknown. I like it too.
The game with stunning visuals. RYSE Son of Rome. No, thanks.
