Yea, only issue is, as we have said over and over again, apparently not many people know any characters in Gotham Central. Do you really want someone to play a character they have NO idea about? If it were an RPG like UDC, where you basically make the character what you want them to be, that is different.
For example, I have read the newest version of Brother Blood's appearances, and Despero's as well...but I didn't really know the characters. But in an RPG like UDC, you don't have to necessarily. Reason being is because you change things about them but keep the main thing that makes them who they are.
Whereas with WSS, all those cops and families you guys list out? If you haven't read Gotham Central, you are screwed: wiki can't really help you. The player cannot change things about those characters.
EDIT: I realize some Bat Rogues have been slightly skewed, but that is a lot harder when you are talking about a cop or mob boss. What can you really change about them? You have to know the characters.
