I think it's also worth considering the fact that video games and movies are vastly different mediums with differing "languages", so to speak. Writing a movie and writing s video game are two very different ways of writing with differing requirements, so just the fact that someone writes good video games doesn't mean they'll write a good movie.

That said, while I know Nojima's responsible for the game script, I don't think the same is true for the movie, so realistically speaking, the writing of the movie is in no way indicative of the writing in the game. The lore and world building is shared, as are some character profiles, but I imagine that's it.
