Gameplay doesn't lend itself to storytelling because it involves a lot of repetition. In the Legend of Zelda, you explore dungeons. In Super Mario, you jump on enemies. In Mortal Kombat, you mash buttons. Even if there is variety, you're doing the same thing throughout the game. And that's fine because part of the fun of gaming is learning, and you learn through trial and error.
Movies, as stories, are more dynamic and less personal. You can't experiment or get a Game Over in a movie. It has to be right the first time. Since games involve trial and error, movies based on games would lack what we enjoy about the games: challenge.
The game I think would have the most success being turned into a movie is the Metal Gear Solid series, largely because they already have such long cutscenes. But a Metal Gear Solid movie, in order to advance the plot, would have to forego the long, drawn out sneaking battles (essentially cutting out the part of MGS that everybody knows and loves) or include it in the film, which would be boring.
