> i think that's why plot-rich video games are so popular as an alternative means of storytelling - they're based around really good writing, but also involve some core interactive mechanics that keep the audience engaged, challenged, and empathetic rather than distracted or frustrated
I'm not sure I agree here. The power of a medium is not in its ability to tell a well-written story, because such a story can easily be made good in any medium. Instead, it is in the ability to make what is a mediocre or fairly cookie-cutter story into an engaging one.
For video games, that feature is essentially interactivity, or the ability of the player to feel that they are actually causing the story to move forward. Ōkami is a game whose story boils down to an anthology of Japanese mythology and folktales with a loose framing device, but is widely praised for the fact that its core mechanic (the use of calligraphy to attack) is tightly intertwined with its graphical display and underpins the framing portion of the sory it tells. Return of the Obra Dinn tells a story reminiscent of any urban legend of a ship's disappearance, but what makes it interesting is that you experience the story backwards and only short snippets of it as people die.
