Videogames are known to improve hand-eye coordination but can they help someone quit smoking or lose weight?

Hot on the heels of Nintendo's smash success, 'Wii Fit', game makers are introducing new titles with a healthy focus, such as French game publisher Ubisoft's "Allen Carr's Easyway to Stop Smoking" that hits on Nintendo DS in November.

Over 10 million smokers worldwide have turned to Allen Carr's Easyway books, clinics or DVD in order to stop smoking but now smokers wanting to quit can instead play 14 mini-games.

The games, designed by Ubisoft's Quebec studio and Allen Carr's team, focus on why people smoke rather than why they shouldn't. "Each game has been designed to be very accessible, using only the stylus on the Nintendo DS, so a non-gamer can have fun instantly," said Denis Dore, producer of the game.
