It has been said that it is impossible to make a game about superheroes, because everyone wants to be Batman. Well, I suppose when everyone isn’t trying to be Wolverine. Anyway, for the first time, everyone can now be Batman!
In this case, everyone gets to be a slightly different version of Batman…from gravelly throated Dark Knights to campy public service message 60’s Batmen to Scarlet Pimpernell-inspired fisticuff pulpy Detectives-In-The-Night. Sure, the comics may have proven that Batman could possibly beat Superman in a fight…but who wins in a fight when Batman meets Batman?
Don’t try to figure out how your universe has multiple Batmen and Bruce Waynes…it just is. Make the most of it. And don’t worry too much that in the comics, most likely Batman would only get “the good dice” during his scene; remember the other Batmen around the table already have a contingency plan for whoever has spotlight.
