What's The Game In Ender's Game?

In IO9 I read that Chair Entertainment Group is planning on developing a series of games based on Orson Scott Card's novel. It is unclear yet if they intend to emulate the games played by "Ender" or that they will tell the story contained in the novel in game form. The company does say that the first game will be based on one of the games that Ender plays during his training.

Humm, sounds interesting, I would be interested in trying something like that out, just to see their take on that portion of Ender's "training"
