alt Hacker NewsIt'd be interesting to see if something like that could be adapted to the screen formats the author is complaining about here. House of the Dragon faced a similar problem. The source material is a lot like what you describe, a fictional history written as if it was real historical research, with multiple conflicting sources, disputed accounts, and no way to resolve the truth of what really happened. The HBO television adaptation kind of just threw that out the window and presented what is supposed to be seen as the "real" history through a normal God's eye third-person narrator. It also showed what happens in situations that the fictional history had no account of, resolving mysteries of what happened to people who disappeared without anyone involved witnessing how and writing it down.
I think there is a pretty significant chance that someone _does_ make a TV series out of it, and it's almost ideally suited for it because it's all background material, so there's a lot of space for a showrunner to actually put their mark on it, and you could probably mine seasons of drama out of it.
Although if they haven't made the Kim Stanley Robinson books into a tv series, it would seem weird to start with this one..
