Sure it does. Choose Your Own Adventure books.
Let's take an example of Phoenix Wright: Ace Attorney, a highly narrative driven game that basically consists of making choices that show different scenes, with some of them leading to a "false ending" of sorts, and most of them leading one way or another up the same, main branch.
There are plenty of youtubers who have uploaded Let's Plays of the entire game, some of whom include alternate choices for viewers who want to see what would have happened. If you want to experience all the content the game has to offer, you really only need to watch a Let's Play.
Is this really fundamentally different from someone who uploads an entire Choose Your Own Adventure book? We can even account for the LPer's commentary by saying the upload has been annotated. It would be a violation of copyright. Maybe the copyright owner will look the other way because it will bring their work much needed exposure, but they are well within their rights to request that it be taken down.
This is the exact grey area where Let's Plays exist. There may be some disagreement over how applicable this is to all sorts of games (it's not a great analogy for a game like, say, Civilization VI) but it at least seems applicable to some games, and Firewatch, as well as a lot of very popular LP'ed games, are a lot closer to something like Phoenix Wright.
