Things like depression and obesity are global challenges.

I want gaming to be something that everybody does, because they understand that games can be a real solution to problems and a real source of happiness. I want games to be something everybody learns how to design and develop, because they understand that games are a real platform for change and getting things done. And I want families, schools, companies, industries, cities, countries, and the whole world to come together to play them, because we’re finally making games that tackle real dilemmas and improve real lives.

What's really amazing about games is how they change our emotional response to challenges

The idea of the 'lone gamer' is really not true anymore. Up to 65 percent of gaming now is social, played either online or in the same room with people we know in real life.

I've been running since high school. My boyfriend was on the track team, and I'd run with him.

A game is an opportunity to focus our energy, with relentless optimism, at something we’re good at (or getting better at) and enjoy. In other words, gameplay is the direct emotional opposite of depression.

If you can manage to experience three positive emotions for every one negative emotion … you dramatically improve your health and your ability to successfully tackle any problem you're facing.
