As Antonio Banderas said in Desperado, "Let's Play"

There have been a number of stories of late on games on international development and sustainability.

The Village: MMOG

No, not that movie by M. Night, but a massively multiplayer online game (MMOG) “that immerses the player into the role of an entrepreneur building companies to bring prosperity to the villages” in developing countries. [The demo is not ready yet.]

Computer and video games have captivated the hearts and minds of millions of people around the world. Games today, in fact, are the fastest growing media form. People are interacting with them in arcades, at home, in schools, online, and on the go, using portable game players and mobile phones. No longer do they only constitute sedentary activity. Innovations like Nintendo’s Wii wireless console get people on their feet and playing the game with their whole bodies, and several games are being used in physical rehabilitation exercises with patients.

RWJF’s Pioneer Portfolio has supported work in this area for a couple of years now, and we have tapped a groundswell of interest in moving games beyond the entertainment realm to help them become powerful tools that help people learn about, manage, and improve their health. The sophisticated graphics and technologies that go into such games also provide a wealth of opportunity for helping doctors and nurses, public health officials, emergency responders, researchers, and others to deliver better care.
