Watch Dogs, a new title from Ubisoft Montreal, was just announced during Ubisoft's pre-E3 press conference. The game looked remarkably better than any console title we've seen to date. It looks like there may be drop-in-drop-out multiplayer, which is always a welcome addition.
That's why it looked so good.
As for me, I hope that this gets a Wii U release as the hacking elements would be cool with the controller.
