McGonigal J. (2011) Reality Is Broken: Why Games Make Us Better and How They Can Change the World - The Penguin Press (New York)
Practical Advice for Gamers by Jane McGonigal Reality is Broken explains the science
behind why games are good for us--why they make us happier, more creative, more
resilient, and better able to lead others in world-changing efforts. But some games are
better for us than others, and there is too much of a good thing. Here are a few secrets
that aren’t in the book to help you (or the gamer in your life) get the most positive impact
from playing games. This practical advice--5 key guidelines, plus 2 quick rules--is
scientifically backed, and it can be summed up in a single sentence: Play games you enjoy no more than 21 hours a week; face-to-face with friends and family as often as you can;
and in co-operative or creator modes whenever possible.
