I have not, but I just left a development-meeting to discuss who all we could interest in the piece. Tourney-communities would be an excellent direction, yes, especially since a game-tournament is portrayed in the second act...but I don't know fighter-tourneys well. I think EVO's a pretty big one, too...?
Other businesses of interest (besides Child's Play and local hospitals if CP gets on-board) would be game companies and reviewers. Nintendo, Valve, and Capcom each have various references through-out the play, so maybe they would be interested. If I find the right reviewer, it could potentially get some national articles as well; agasonex seemed to have a similar success with Chester.
