Games and Civic Engagement

While listening to the presentation about computer games and civic engagement, one thing struck me: kids who were already active or interested in civic engagemnet were the ones playing those strategy or civilization building games.  So if they were already interested, what is being done to interest kids who are otherwise not interested in civic engagement through these games?  Wouldn't that be the whole point about encouraging or taking advantage of an existing technology to teach students/people lessons and skills and benefit our socity?

How is playing the games helping the kids who are already interested in civic engagement?  I know that they experience decision making under multiple considerations, but is this skill/experience transferrable in real situations?  Do these kids make better leaders in the future?  Is there any data?  I hope there will be studies done on them....
