This catalog details the extent of NASA’s game portfolio, so that others developing new games are able to build upon the lessons learned from the past. Enclosed herein are details on fourteen individual games that have been created by or for NASA as well as two collections of hosted Flash games. Each entry has information about the game, including a screen shot, point of contact (if available), and a link to the game’s site. The games are identified by genre, NASA content or contribution, and intended audience or Entertainment Software Review Board (ESRB) rating.
