Tipping Point for Meaningful Games?

Normally don't comment on my other worlds, but must share how happy I was about the turn out for this year's Games for Change Festival.  When even the Honorable Sandra Day O'Connor is talking about creating games (Our Courts), something has moved beyond the once small niche of folks reimagining how games can create social impact.  Still many (interesting) challenges in embedding values into design, but lots of emerging projects are happening and intersecting various fields.  Aside from typical do-gooders, increasingly corporations and venture capitalists are also showing interest and investing in platforms and projects (see Microsoft XNA based Imagine Cup, AMD Changing the Game, and Akoha).   More at Games for Change.
