In an interview later that day, Guay told me that the titles are very similar across platforms, even, in some ways, across generations. When I asked Guay to explain the differences he said it was easier to start with what's the same.
"So it's the same storyline," he said. "It's done by the same team, so it's not a separate team in another continent that was (making one of the versions). So, same storyline, same gameplay, all the same mechanics, innovations. All the same missions, if you want, the same world.
"Obviously what's different, is that we're scaling the dynamism and the detail of the city and the gameplay. So it's stuff like the amount of civilians in the street, the amount of cars in the street, the detail in the animation, or how sophisticated some reactions are to some of your actions. So some of those things are scaled down. Obviously the graphics, but that one's obvious."
