How is Firefly: Misbehavin’ different from Firefly the Game (and other deck builders)?

About Firefly: Misbehavin', from BoardGameGeek:

Someone ever tries to kill you, you try to kill 'em right back! In Firefly: Misbehavin', players get to control different factions of the Firefly 'Verse, from the criminal enterprises of Badger or Niska, to the self-righteous Alliance, and even Serenity as Mal attempts to find a crew and keep flyin'. This deck-building card game gives each player a unique starting deck of cards, as well as access to characters, items, and locations in the Core, Border, and Rim. Compete to control your own corner of the 'Verse, or play through different episodes with a wide variety of objectives. -description from the publisher
