Today the PLACE cards especially are just static content holders... they aren't gamified in any way.

It could be interesting to allow players (perhaps as a shared pool to avoid over use) the ability to play a PLACE card (or a character card for that matter) once they have encountered that PLACE or CHARACTER card.

For example, if you visit "The Secret Weapons Lab", it would be nice later on when encountering "Mob Boss O'Dooley" to play down "The Secret Weapons Lab", narrating "I tell O'Dooley I know where the secret lab is... and the info is all his if he just gives me what I want right now.
