Watch a crazy drone race in Watch Dogs 2
For one it's following on from a high profile title by one of the biggest games developers in the world that failed to really make its mark. We're hoping that this series follows a similar pattern to that of Assassin's Creed- an interesting concept at the start which was refined and improved on hugely in the second outing.
One thing Ubi is working on is giving you more to do in the open world setting for the sequel, and that includes fun stuff like drone racing. Fun was in short supply in the first game.
