Anyways, who are you expecting to pay for these educational games? Schools are receiving heavy budget cuts, and you're not a trusted educator (as far as I know) that knows the curriculum, which varies quite a bit by place.
Education isn't really a "genre" because it doesn't describe the game play like "shooter" or "platformer" does. It's more of a purpose. I think that educational games aren't as fun, by nature, because they try to serve two masters: fun and education, where one or the other gets the short end of the stick.
