I've played through a couple times, picking up something new on each playthrough, but I'm attempting to pay especial attention to detail on this run through (thanks to Kyburz for ideas of which limitations might make the game more interesting).
So I get into the Fisheries, and ol' Peachy, after spewing out his speech about the Devil and Fontaine says: "Atlas was ours! OURS!!" Now what could he have possibly meant by that??
