Guardian.co: "First, video games can improve basic comprehension in a way that isn't painful for a student who struggles with reading. To see words on screen and engage in the actions associated with that text is a very simple, straightforward way to develop and practice reading skills.
Games can also help players develop other skills. For example, a game like Call of Duty, which is a hugely popular series, can be viewed on one hand simply as violent because it's a war game. On the other hand, if you've ever actually played the game, you'll notice that it requires a significant amount of strategic know-how and team cooperation, things that are not as simple as they seem."
