If I make a game with a very serious plot, how will you rate it? What does "serious" even mean, other than the game's plot?!

let's be real. The process of truly understanding a story takes hours. currently there are 2250 participants. 

And story is part of everything else. Story is part of your creativity, visuals and audio.

If your story is that amazing, everything else will be amazing too probably.

I consider story to be a part of general enjoyment :) Maybe it's mechanics that make a game fun, maybe it's the story, etc. If this is a common piece of feedback though I will definitely consider it in the future
