Hmm I'm not convinced by the people arguing games are stories, but playing live on twitch so other people can watch might be a new medium. To me story consumption is fundamentally passive, vicarious identification. If you have to make decisions it's not a story.
I think this is an is/has confusion. Videogames are not stories, but they have stories, and in having stories provide an interesting medium for conveying them, even if that's not all that they are.
That's a very questionable distinction if one is thinking about stories. You're imposing commodification categories on a continuum between creation and consumption.
It is empirically false that no one plays video games for the story; many people play no other part of them.
And in many cases there are no meaningful decisions in that story, either.
Also there was a book genre "choose your own adventure", which was clearly story.
Most games w/big narrative component don’t let you fundamentally alter the story. You might have a choice of intermediate goals at diff stages, & you can succeed or fail at each. But the major beats happen in a set order. Everyone who “wins” has generally been told the same story
