Game developers know that people have more fun when they're in large groups. They feel more fired up when the challenges are more epic.

Gamers always believe that an epic win is possible and that it's always worth trying, and trying now. Gamers don't sit around.

Game designers are obsessed with emotion. How do we create the emotions that we want gamers to feel, and how can we really make it this intense, emotional experience?

When parents or gamers ask me, 'What's the best game to play?' I say that playing face-to-face is more beneficial than playing online.

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.

For most people, an hour a day playing our favorite games will power up our ability to engage whole-heartedly with difficult challenges, strengthen our relationships with the people we care about most - while still letting us notice when it's time to stop playing in virtual worlds and bring our gamer strengths back to real life.
