It had a more of an impact than that. I remember talk of the girls fighting the heroes. As well as the heroes showing up at the Glamor Slam. The defense of the labs was obviously scrapped. I remember Jimmy Olson even popping up on the danger meter . So there was obviously changes made to the game play. That's why I was just wondering what all effects the CnD letter had.Sunset has pretty much said multiple times that all it did was force them to change the name. Nothing in development really changed to "protect" the project.
They did eventually stop with monthly builds but that was more from Sunset getting tired of adding content for 2 weeks and then have to switch over to plugging it in. Wasn't a healthy work environment
