Anyone know any good case studies or reports detailing the benefits (or lack there of) for content websites that add game mechanics (badges, rankings etc)?
Hi, there is a book on this topic:<p><i>"Gamification by Design: Implementing Game Mechanics in Web and Mobile Apps"</i>, written by Zichermann and Cunnigham, from O'Reilly, August 2011.<p>The description on amazon mentiones case studies. I haven't read this book, I have just seen it in the book store, so I can't tell you if it is good or if it is what you are looking for. There are no customer reviews yet, but I hope that this information helps.
