They really should look to make a tv show out of a video game
The reason I say this is because video games normally are 10 hours to 20 hours and if we're talking rpgs 40 hours(main quest) to 120(main and side quests).
TV I feel is a better medium at this point then film because you can tell a longer story then a feature film. Plus a lot of tv shows are actually better then film and a lot of talent are going there.
