Victoria Rules
An equivalent would be trying to run a Middle Earth campaign having only seen the movies, then having a player start going on about some guy named Tom Bombadil...It's starting to sound like some of your players might have known more about the setting you wanted to run than you & you weren't interested in learning. If your wanting to run a game strictly confined to a specific setting expect a world of hurt if you haven't even started reading the books when your players start leveraging knowledge from them..
