I love the idea of learning from games! There are a lot of edtech companies out there trying to bring technology into the classroom, but I find they tend to be pretty gimmicky. They slap on nice images onto apps that are essentially just glorified flashcards. It makes sense that teachers don't trust them.
But I do think there's potential to improve the quality of the games. One of my favorites as a child was Treasure Mathstorm. It was simple and taught math, but as a kid I didn't think of it much as an "education" game -- it was just something I played for fun. And that was in 1996 - imagine what we could do now! We need more of those out there.
