Betrayal Legacy marries the concept of Betrayal at House on the Hill — exploring a haunted mansion — with the permanency and multi-game storytelling exhibited by Daviau's Risk Legacy and other legacy games that followed. Betrayal Legacy consists of a prologue and a thirteen-chapter story that takes place over decades. Players represent families, with specific members of a family participating in one story, then perhaps an older version of those characters (assuming they lived) or their descendants showing up in later stories.
