Pretty good slide show on the impact and potential of games to support learning and change. The slides, by Jane McGonigal, refer to "World Without Oil" and "Evoke" (which I've been following as it moves into its third week online) as examples of massive multiplayer games that can support change. But what change? Whose change? I see the stamp of the World Bank all over Evoke, which to me creates challenges of bias and perspective. And there is the danger that these presumptions are implicit in games (see my post Sensitize / Desensitize for a summary of these concerns). More slide shows from McGonigal. If you have lots of time for TED eye-candy you can watch a video of one of her talks. Here's her most recent post on Evoke.
