This is a pretty interesting article, but hardly breaking news. I have been using game projects to create interest and build enrollment for years in my Computer Science classes. It is good to see that this approach is gaining wider use as games are appreciated by almost everyone and can get students very excited about Computer Science. Board Games make great projects and do an awesome job showing the students why objects are important. GridWorld makes for a great game platform in the AP CS A class. Scratch and Alice work well also and allow students to build scenes and incorporate a story into the game.
