"smarter in what they do" and how they react to the player.
We can also expect to brush past a lot more of them on the streets. Of course there are also visual leaps with water "far more realistic on next gen," as it flows and breaks.
Despite being much closer to how PC architectures run, senior producer Dominic Guay says the hardware is still fresh and will take time to master and squeeze.
"There are obviously quite a few differences," remarked Guay.
"There's graphics, of course, but there's also the dynamism of the city. For example, the water is far more realistic on next gen, the way it flows and parts when you drive a boat through it. We also gave better brains to NPCs, they are smarter in what they do and how they react to the player. Plus, there is a lot more of them on the street at once."
"The hardware is still new and it's obvious to us that it is going to take a while to get to the full power and harness everything. What is clear is that both systems, PS4 and Xbox One, have comparable power which is good for us as developers." Watch Dogs releases on Xbox 360, PS3, Wii U and PC November 22nd.
Xbox One and PS4 versions launch later. The big question now is what camp does PC fall under?
