On graphics, time-of-day action and shadowing: "We've done a lot of work on the graphics from a technical standpoint. We've completely rewritten the render pipeline. The detail and the scope you now see, we couldn't get before. Like, in the desert, there's tumble weeds and so forth, really organic stuff. There are tons of unique interiors, a much more densely populated map. There were bits in the Vice City map that we felt were a little under populated. And even in the countryside, it feels like there's more possibility for action. We've got real-time reflections in mirrors, we've done a huge amount of work on the lighting system. We were pioneers in the day-to-night clock system. But now it's a lot better. There's a totally separate model for anything in the day-time and anything in the night-time. So you get a much better feeling of night and day, a much better contrast. There are shadows, which give us a gameplay thing we never had previously, because you can hide in them. Now you can sneak in a GTA game for the first time. You can have a mission where you can play it balls out with a machine gun, running and trying to blast everyone, or you could sneak around and pick them off one by one. It gives a lot of choice."
