Another truth is that you don't need a good story to achieve success. There are many successful games with no good story or no story at all.
"Story in a game is like a story in a porn movie. It's expected to be there, but it's not that important."
The guy is so deep in code engineering that sometimes other, more nuanced, details can be seemingly totally lost on him.
Of course, it can fail too, but in my humble opinion it is one of the best approach to game design.
Some games focus on mechanical skills or rules akin to a sport or boardgame, others are an interactive narrative experience. This interactive experience can further be broken down into games that tell you what is happening (cinema), and games that let you make your own story (tabletop RPG).
So while there is a lot of crossover and blurred lines, of these types of game, only one type really needs a well written or scripted story to achieve its goals. We have many successful games with no story due to this, but other games wouldn't have succeeded without one.
Space Invaders, Pacman, Mario, Tetris are games that single-handedly defined an entire generation of games. No story to be found.
I think the OP is perfectly on point. A good story demands an authorial voice, and most games can't have (or won't bother with) that.
