Ask HN: Reports on adding Game Mechanics to websites
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)?
"Gamification by Design: Implementing Game Mechanics in Web and Mobile Apps", written by Zichermann and Cunnigham, from O'Reilly, August 2011.
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.
