Nice idea. I've been thinking lately that the much-maligned genre of "edutainment" is going to come back tremendously now that games are cheap and quick to make for any concept you might want to learn.
Unlike normal game projects, they don't need to be as raw fun as a professional game, nor cover a popular-enough topic to be sellable to others, they just need to be fun enough to make you stick with the learning process for an afternoon.
