It's always fun to see what lurks just below what we can see in a video game through datamining and the like. You can find remnants of ideas that hit the cutting room floor, or perhaps suggestions of what's to come in DLC. A lead developer on Assassin's Creed Black Flag Resynced respects the curiosity, but asks we don't put much stock in what's uncovered.
"Many games get datamined, it's very clever, I understand," Richard Knight, game director on Assassin's Creed Black Flag Resynced, says in an interview with JorRaptor (below). "Sometimes these are for assets that don't even exist yet, and sometimes they're placeholders that were done three years ago."
