And to be clear, for right now only one character per person is allowed. 

I don't want people to burn themselves out trying to write multiple stories at a time - I know how tempting that is, given I'd love to play about a dozen other heroes alongside Batman, but I also know how daunting that would be. I'd rather just stick with who I want most and give my all to that. 

If this game makes it to a Year Two, then the idea of expanding character slots can come up. Or if we somehow do really well and there's a serious void still needed for major characters.
