It is very important..
If the game lenght is long the story must be really good.
Good story may save even mediocre game and lift it in A class game.
Or a very good game which story is rubbish cant`t enjoy much.
Also there different game types that need good story to keep going.
Worth to mention is how the story is told..Is it talking heads, in-game conversation, or you read it it games interface (aka Metroid,Bioshock)
