Ubisoft hasn't decided how Watch_Dogs will use Wii U GamePad

Creative director Jonathan Morin told Kotaku that Watch_Dogs will give players "the same experience" on all platforms, but that doesn't mean they will be identical. The Wii U version will almost certainly make use of the GamePad in some way, allowing for an experience not possible on other platforms. Senior producer Dominic Guay told Digital Spy that Ubisoft is currently considering how to implement the GamePad's unique features, but he emphasized that the "core" of the title will be the same on all platforms.

We’re still investigating how we’ll use the tablet on the Wii U, but with the things I mentioned before, for us it’s not going to be a weird stretch. It’s natural. What’s really cool with Watch Dogs, when we start thinking of those devices, it’s not a weird abstraction, it’s not like I’m a space alien and now I’m using a tablet. Why am I doing that? Aiden Pearce is using a device to control the city, so it’s quite easy to imagine what we could do with that.

So the connectivity between players with mobile devices, the way you can control the city, the immersion, all those are core and on any platforms we’re going to ship on we’re going to make sure we nail those pillars down.
