I'm talking primary/early secondary level. (say 9-14)
The AI editor is a great primer for AI programming and is incredibly easy to pick up. Plus the game is currently very cheap, which schools would love, and the kids will love the fact that after they create their AI they get to see it in action in the form of robots blowing each other up.
I think it would also help with word of mouth and the game is already good to go for that purpose. (Well it might be preferable to wait until private matches as the teachers will probably want their pupils to compete against each other as they can then compare the AI's afterwards so the pupils can see why one won)
