Reality is Broken - reading

Finished "Reality is Broken: Why Games Make Us Better and How They Can Change the World" by Jane McGonigal. I was torn between a 3-star and 4-star rating (out of five) for this one, but decided ultimately to go with 4 stars because the parts I didn't like about it were still very well done and deeply researched. The reason I didn't like those parts was mostly that they were beyond the scope of games or impacts that I was thinking about going into this book. The other reason is that I liked how it started off talking about theory, and then devolved into a bunch of examples that didn't resonate with me. What will I remember? Tombstone Hold'em!
