I think games are now the new way of giving audiences adult animation, since most movie studios don't risk animated movies that can't won't appeal to younger or a wider audience.

That being said, gaming and cinema are two different fields of story telling. While games have become more cinematic as tech improves, they still have to utilize a story that works around the mechanics of the gameplay. So a game may take it's time for a story element to unravel and use the player's interaction of the world as the catalyst that triggers story elements.

This is another reason why so many video games movie fail to really capture the story structure of the games. Resident Evil is a scary game, but you can't adept that fear you feel playing the game to a movie. The reason being is because that fear you feel is of your interaction with that world in the game and how you react to the situation you're thrown into.
