Legitimately curious, what is lacking from current playthrough and movie descriptions available now? For games the only things I feel like might not be represented well in text is descriptions of the observer/player reactions and maybe details about their specific choices through a game... Kind of like turning a choose your own adventure book into a normal book by tracing one path through it?
I can see Q&A on a movie being useful but can't think of descriptions of the overall movie itself lacking... I'd definitely be worried about spoilers.
