1.) At the onset of the reading McGonigal talks a lot about games improving our lives, new types of games that would save the world and I my question is what kinds of games will improve the world? Are there existing examples of this? If so how have users responded? And lastly what is the users motivation to begin utilizing these types of games?

2.) McGonigal touched on the point that game designers try to prevent addiction to games and try to promote the balance between gaming and real life. My question is what do game designers do specifically to prevent addiction from happening to their users?
