You could drum up some interest soonish, what with the animated series ending in a couple weeks and that's sure to bring muses out of the woodwork, but I'm just seconding the above anon. The idea is good, and I'm sure characters would make great lanterns, but the only Corps with easily obtainable info is Green. Mostly thanks to the movie and Greens being major players in all the other DCU stuff that comes out because there's at least one Green in the League at any give time, but the game wouldn't get far with just Greens everywhere.

Unless there's some source you could give players about the other sections of the Corp, like a detailed wiki, I honestly doubt it would get anywhere worthwhile. It's a good idea, and another superhero game would be a nice thing, but there's just too little info for those of us who want to be more legal than downloads/torrents and don't have access to a comic store or digital purchases. Just sayin.
