Some interesting tweets from Jonathan Morin, Watch Dogs creative director.

translation from pr bullshit:
-there are side missions
-but they arent fleshed out with individual stories that span a good chunk of time
-they are "dynamic events" like someone getting mugged or someone talking about [an item] they left somewhere
-random people will get mugged 10000 times as you walk around the game, and someone off screen will suddenly complain about not being able to find an item 100000 times
-its up to you whether or not you want to decide to keep wasting your time with these throwaway dynamic events for little reward after youve already done them ten times or more. theyre all the same fucking thing except you can choose to use a bunch of alleys to get there or take your car
-after you've seen the three or five or so different encounter variants of our RADIANT AI youve seen them all
-tl;dr remember all the great DYNAMIC side missions from AC:R? remember Skyrim's MISC quest tab of quests that have zero story and just make you do repetitive meaningless shit? its back
