Kazunori Yamauchi recently previewed Gran Turismo 5 Prologue at the Games Convention 2007 in Leipzig. He dished out a number of new details that will no doubt get fans of the series excited.
The most asked question in terms of gameplay for Gran Turismo has been whether or not the cars would support damage. When questioned on this, Yamauchi explained that a damage model is being worked on which heavily involves A.I. He went on to state that GT5 is very different in terms of A.I. in that it's fundamentally linked to car damage.
The A.I. is more aware of the track and the turns in it that can cause damage if cars make overly sharp turns. Therefore, the A.I. has a lesser tendency to fall in line, something which can cause a lot of damage.
A North American release has not yet been confirmed for Prologue. However, Japan and Europe should see it on PS Store before the end of 2007.
