Netflix’s short stint with FMV / chooe-your-own adventure games highlights a perfect case of difficult preservation - all the runtimes are closed source apps, all the data is streamed from a server, and all the logic is held on the server.
Add to that the fact that a lot of these types of non-standard content have low engagement and interest. Which is what ultimately makes preservation and piracy harder. If you had a lot of interest it would be difficult but not impossible to recreate some of the interactive elements around them, and extract/decrypt the video content. But without interest it’s more difficult. Also ironically the lack of interest is why these things are being sunsetted in the first place. It’s kind of a perfect storm in that they are hard to preserve and there is also low interest in preserving them as well.
