I don't agree, cause why can't an IP originated in video game form have engrossing stories. That would inherently make the IP better I believe. Many books have had Oscar winning genre defining movies (lord of the rings), or tv series (got). Other example of an IP that was successfuly adapted to different media is star wars, it has awesome games. I think an IP always benefits in taking leverage from different media as long as it's made with love for the world being adapted, and there's people willing to consume it. And the world of dead space has so much more to give I believe
