I can't find any games called "Ancient Mystery's" or "Ancient Mysteries" or "Ancient Mystery" using the Big Fish search.
Is this about the "Mystery of the Ancients" series or possibly a different series that isn't available at Big Fish?
The "Mystery of the Ancients" games I see at Big Fish are
Mystery of the Ancients 1: Lockwood Manor
Mystery of the Ancients 2: Curse of the Black Water
Mystery of the Ancients 3: Three Guardians
Mystery of the Ancients 4: Deadly Cold
Mystery of the Ancients 5: Mud Water Creek
According to
***rgamereview.com*** that is the order in which they were published.
