I can understand the benefits of expansion on minimal narrative, it can have some pretty solid results*. But it is also how movies like the JCVD "Street Fighter" and "Super Mario Bros." films came into fruition. It can go both ways.
*I remember when Namco/Bandai had the ShiftyLook website for a while a few years. I think their webcomics were some of the best examples of taking a minimalist game narrative, and making some solid serialized stories out of them. They even ended up adapting the Wonder MoMo comic into a short lived anime. Good stuff.
