Kotaku just had a chance to sit down with Gran Turismo series creator Kazunori Yamauchi to not only watch the Polyphony Digital president play some expert-level Gran Turismo 5 Prologue, but catch up on how the teaser version of Gran Turismo 5 will play. The early taste of the first proper PlayStation 3 release will feature a number of firsts, including online play, damage effects for cars, and fully modeled interiors.
Also at the behest of fans is a working damage model, one of unspecified depth. Kotaku didn't see Kaz run into anything during their session, so it was hard to tell if the game features the system in place yet. When asked about the new built-from-the-ground-up AI code and the option for car damage, Yamauchi indicated that CPU controlled drivers are aware of the new penalties for playing "bumper cars." With up to sixteen cars on the track, they need to be aware of each and the danger of spinning out when one comes in contact with another.
Yamauchi says these changes will lead to fewer cars lining up as they had in previous Gran Turismo games.
