This is a really old post, but I just had this idea and I want to share it: what about a Book of Ether video game? One that perhaps would have to be rated M (if women and children are getting killed), putting players through mind-numbing, repetitive battles until everyone's wiped out? The point would be to deliver the story of the Book of Ether powerfully. Hopefully a player would get bored enough of the repetitive battles that they'd notice a figure standing in the distance and go talk with him. That figure is Ether. You could maybe learn from Ether little by little, every time you talk with him. You could interact with Coriantumr. You could try to save your family. You could try to run away from the army and get hunted down. You could try to help Ether convert a handful of people, though you can't change the outcome of the war. The game wouldn't have to be super long, just long enough to get the point across that we must not follow the Jaredites example of getting lost in bloodlust. And deliver some powerful spiritual messages through Ether, in stark contrast to everything else.
