The scenarios, as well as the adventure path "card" and the adventure "card" in this product are more than corresponding cards in the base set. Each is a full page of information. In addidtion you get 3 villain cards that are used in the scenario.
You do not need anything beside the base set to pay. You only need class decks to play if you want to play this in offical PFS form, but they can come in handy in normal play as well.
Thank you very much for the answer!
