Wow. Even the name of the game was plagiarized. I didn't read the whole thread, but I did notice that the main character is Captain Benjamin S. Briggs, the real life captain of the Mary Celeste, a ship found abandoned in the Azores, the story of which is documented in Limbo of the Lost by John Wallace Spencer. Crazy stuff.
EDIT: Ah. I see. The game is actually about the Mary Celeste and the same Briggs.
EDIT: Now I've got to run to Fry's or Best Buy to see if I can find it on the shelves! ;-)
