What do people think in the way of story? I'm not enamoured with having some over-arching meta arc or event mandated by the GM. I think for the most part it's better to let things work themselves out.

I'm quite keen on Luthor financing the Justice League and having Superman, Batman, etc. on the outside looking in to begin with, with Captain America, Thor, and others on the JLA. Publicly Luthor isn't remotely suspect at this point. He's a reputable business, perhaps only with Superman suspicious of him, and the Justice League have spent the past few years dealing effectively with the mutant menace. But like I said, nothing is concrete. I want this game to be as much yours as mine.

Feel free to throw out any wider IC ideas you might have for the game as a whole.
