If anything I'd say a movie license in the world of gamers is a chain around your neck, because there haven't been a lot of films that made the jump well. Mad Max did well because it was a legitimately good game, and while Metal Gear was a big deal, its not as big on the PC as in Sonyland.
NVidia had been bundling MGS with all video cards using their chipset for a good part of the year. If I read the chart correctly it's not counting the bundled MGS as sales.
