Q&A com a equipa da R* North encarregue do audio do GTAIV:

"The pedestrian AI is much more complex in GTA4 than it has been in previous games, and we have to create dialogue to cope with this - peds now do a lot more than they could do previously, and can react in more ways to what happens in the game.

We also decided to make the pedestrian dialogue more realistic in GTA4. As an example, peds in previous games would walk around and randomly chat to themselves if they weren?t doing much else. In real life, people (generally!) don?t go around talking to themselves, so we dropped this behavior from GTA4. However, we realized that the random chat of old GTA games was a good way for the player to pick-up on what sort of personality a ped has, so we created the cell-phone conversations in GTA4 as one realistic way of portraying personality."
