Why a single-player story with multiple characters? Why no multiplayer co-op?

It would be impossible to do that and keep the level of precision we've got in this. You could make a great co-op game, but we felt that we're doing other bits of our multiplayer that will fulfill those desires in ways we think are very fun.

GTA IV had players making story-based decisions that drastically changed the game; will GTA V?

We don't have the same choices as we had with Niko, for one very simple structural reason. Just keeping track of three stories as opposed to one story means it's harder to introduce a variable. You put a variable in a certain place and it just made our minds spin.

Why aren’t Kinect and PlayStation Move in GTA V?

One of the things we're doing now, just to talk about mini-games, is making sure when you go into the mini-games and when you come out of them it feels very seamless. It feels like part of the whole experience. If you were suddenly go, "This bit's Move, that bit's not, this bit's Kinect, that bit's not," it would feel very disjointed to us. That would be detrimental to the overall experience in exchange for a bullet point on the back of the box. That's not very appealing to us.

On the GTA V Map:

This world -- the range of height and between north and south and east and west -- is huge, and it's a real strength. It felt California. Oceans are there and tall hills are there. We wanted those in the game. For us, this kind of world, that was a big properly-realized L.A. and a huge slab of regionally appropriate countryside, felt like the most interesting match to do something new with. Doing other cities just didn't seem appealing. Doing small towns is very appealing.

Will we see characters from GTA IV show up in GTA V?

Packie's not in it. There may be the odd... They tend to be very small. The problem is that... You touched on this earlier. Because of a lot of the choices... We've never had a game where we've annihilated so much of the cast. 

So many of them were killed that we didn't really have a large amount of the main cast left over. There may or may not be a few guest appearances. Some really subtle ones for people to find. Little Easter eggs for people.
