Maybe. Maybe not. I think the questions of "who pays", "who profits", and "who controls the material" matters a lot. So does learning theory (I don't think games will be the only way to learn). It is definitely a field we should pay close attention to if we care about learning.

For anybody interested in the space, I strongly recommend "What Videogames Have to Teach Us About Learning And Literacy" (James Paul Gee)
