I'm always fascinated with interactive stories, but ultimately, I'm almost always disappointed in them
I like reading Emily Short's blog on interactive storytelling https://emshort.blog/
But I rarely like a game where I influence the plot
Another possible way to make stories "canon" is probably MMO-ness of the game.
When there is a single world and the devs are like a GM of all the players, making the events canon and updating the content. I wonder if there are games like this that really allow the players to change anything.
Spirit AI https://spiritai.com works on making really good NPCs that feel like people (I think). Maybe that will bring enough complexity so that alternative routes of a video game don't just feel like alternative non-canon universes of comic books
