IGN reports. The publisher seemingly asked players for thoughts on a hypothetical pirate-themed game similar to Assassin's Creed 4 that would take place outside the series. The survey reportedly asked whether customizable ships, characters and hideouts or a "deeper economy" and "additional activities at sea or on land" were more important to players, and also gauged fan interest in co-op and multiplayer naval battles.
Ubisoft conducted similar questionnaires in the past. Coincidentally, the publisher also specifically asked players about cooperative multiplayer in December 2010 following the release of Assassin's Creed: Brotherhood and again in November 2012 after launching Assassin's Creed 3. Both of those polls were conducted by GMI Surveys, though the origins of the latest one is a little less clear.
