In case you were curious, Watch_Dogs will reportedly take around 35-40 hours to complete - as long as you're not the sort of person who must uncover every single secret.
The numbers come from the game's creative director, Jason Morin, via Twitter, who says completists will take closer to 100 hours.
I would say the average player which does free roam a bit tend to reach the end within 35-40h.
The entire development team has been working hard to polish and fine tune Watch Dogs in order to deliver a truly memorable open world game. In parallel, the extra time also allowed the team to include a bit of additional content.
Watch_Dogs hits shelves on May 27th for PC, PS3, PS4, Xbox 360 and Xbox One.
