I always saw Hope, Unity, Sacrifice as the three games: Adventure is Hope, Aeon is Unity, and Aberrant... well they were in a way sacrificed, wen't they?

On a related note, a question: How compatible will the Storypath-variants be? Would it in theory be possbile to take the core book for the Trinity Continuum and for Scion, add in Hero and Aeon or Aberrant, and sotra kinda run The Avengers?
