"Why are you releasing 'Prologue'? Many people don't want to spend their money in what they consider a demo (Note: like there has ever been such a demo with that amount of amazing, amazing content and features.)
Yamauchi: We believe that at our current pace, GT5 will be ready by December 2008. 4 years will have passed since GT4. It's too much time, mostly for the series fan. There are plenty of things left to do. We also have the online features. It's a completely different product compared to GT4. It's way superior in all aspects. We need to test it fully so that it becomes a perfect product. I consider it dangerous, to say the least, to release a game like this one without having subdued it to the toughest quality assurance tests. Also, since it's something so important, I fear of online features failing. That would be a fatal blow. I intend to introduce online features bit by bit. Another reason to release Prologue is the simple fact that it's been too long since GT4. I want to get the user feedback ASAP. And Prologue is a good way to obtain so.
So, when is GT5's launch due? End of 2008?
Yamauchi: Yes, Christmas 2008 is the the planned release date for now. Anyway, it's not final yet. It's been tough to develop Prologue. To get the picture, if my current development team did GT1 again, they would finish it in two weeks. Back then we spent 4 years. It's very hard work.
I see. And the fans also expect that tremendous quality in the new Gran Turismo, right?
Yamauchi: Yes, it's a great responsibility. That's why I want it to be perfect. And that's why I can't tell for sure when it'll be released.
Regarding the vehicles, have they been redesigned completely?
Yamauchi: Completely, from scratch. We have reused absolutely nothing (*emphasis on this*) from previous versions. Everything is new.
[Yamauchi elaborates on how he even wants the back seat interior to be perfect even if the players would rarely see it]
How long did it take to model all the cars?
Yamauchi: A designer spends roughly 6 months in average. 50 cars are 300 months. That's 25 years. The tracks are a lot more work. It's longer than a year each. We have 30 people working on the tracks.
[Yamauchi talks about how PS3 is the system that can provide the absolute best picture and how perfect he wants GT5 to be again, how it'll support Full HD 1080p60, how the players will actually see the very same they'd see if they drove a given car in a given track in real life, etc.]
Regarding realism, when will we see car damage?
Yamauchi: Right now we're testing this. We will see car damage in GT5. There are three problems to solve though. Firstly, some car manufacturers don't care to see damage in their cars but others would never allow that. Some cars will be damaged and others won't, depending on the manufacturer. Secondly, the simulation. In Daytona Speedway, for instance, going slightly sideways when getting out of the banked curve and entering the straight section and hitting slightly the rear part of our car against the sides of the track will make our car become utter junk. Game over. It's a small mistake, but physics calculations tell us we'd undergo a 150 G force. That equals death. The car is literally disintegrated. We do not want that. We do not want to destroy the cars. I don't like that. That's ultrarealistic simulation, but if it happens, the game is over, you lose your car. I'm resisting to accept that kind of effect. Right now we're looking into how to make pure simulation and these kind of situations be compatible with each other. And the third problem, the fact that many driving games out there feature this kind of accidents, but I've never seen one which actually provide something positive or are perfect from a technical standpoint. I've got to think a lot about it yet, but I understand the series supporters do want damage and accidents because, for the better or worse, they're an integral part of reality.
[Yamauchi talks on how they're trying to emulate human behavior for the game AI, and how tough it is to do so.]
Is Sony imposing any restriction or forcing you to do something in particular?
Yamauchi: Just the release date. Till now we had some flexibility in that aspect. I'll let you know we're the movie's villains to Sony. But we don't listen to them that much (*laughs*). Fortunately we have quite a lot of independence. For that reason, GT5 won't be out for sale until it's finished according to my criterion. Sony understands I'm a perfectionist and they allow me that. The hardcore fans would notice if something's wrong in the game. They're like me. That's why I want to perfect it to the max. In terms of conceptual aspects or limits, Sony does not interfere a lot, I have a lot of freedom in those regards.
Would you like to take a breath of fresh air and create a new successful series in the videogame world?
Yamauchi: I've wanted to create an RPG since long ago but I don't have the time to do so. (*laughs and remains thoughtful*)
[Yamauchi says that PS3 has the power but it's still expensive. It features Blu-ray for the future, and says he's very patient.]
Excuse me, but are you telling me Gran Turismo 5 is only possible on PS3 at the moment?
Yamauchi: Yes, exactly. On the other hand, Xbox 360 is not a system designed to support Full HD since the beginning. There are very few 1080p60 games on Xbox 360. It seems like a system designed for the inferior 720p. We're talking about significant differences in this very generation of home consoles. Soon enough people will give credit to the strong attractive of Full HD, of the true high resolution. I want to do videogames that take full advantage of each generation's technical abilities.
[Yamauchi says it would be totally frustrating to develop for Wii because of its lack of processing power and that while people, the industry and media say PS3, Wii and 360 are "Next Gen", the only true Next Gen is provided by PS3].
When will we see Gran Turismo Portable?
Yamauchi: We are developing it right now. It'll be released after Gran Turismo 5. We're going to make it a complementary game.
Will you take a rest after GT5's release?
Yamauchi: Due to the online nature of this game, we still need one more year to get it out. We'll progress day by day. The plan is not to start working on GT6 immediately after that. We'll keep adding features or improving things in GT5 taking advantage of the Internet connection. That's why I won't have time to rest. In these 15 years of Gran Turismo I haven't had any holidays.
[The interviewer asks Yamauchi if he spends any night at the studio and he says it's not the case lately but there was a year when he only spent 4 nights at home].
[Yamauchi says that the Japanese videogame industry peaked in the 80's and 90's and that the current game designers aren't open to true innovation, something he hopes will change].
