For me this depend the type of game.
Strategy game : Gameplay > story & visual art
RPG : I want both on par !
Action/adventure : Story & visual art > gameplay
Fighting : Gameplay > story & Visual art
And sound is really important too, but not in strategy game :)
I want to add, if its not a rpg/strategy game i prefere short good story of 10h, i have hard time to finish long game like gta etc...
