How are you preparing for a Vampire game, set in a post-apocalyptic setting (where I am assuming violence is a more constant and reliable way to solve disputes and where there is a smaller presence of society and, therefore, societal punishment for it), to not devolve into a warzone, if you plan on OOCly cooperation?
Are you sure multiple Princes is not going to dilute the title and the playerbase? Wouldn't the head of the Covenants (if those exist) fill these 'high authority' roles a bit better? Is there a reason to allow multiple Princes other than to let players feel good about the title?
Is the XP capped? How do you plan on handling stagnation once 45+ dinosaurs (around 8 months, not accounting for Beats farmed through aspirations, plots and other means) have a stranglehold on the positions and are the law of the land?
