Joystiq interviews Polyphony Digital's Kazunori Yamauchi

Gallery: Gran Turismo 5 Prologue
Thanks for taking the time to meet with us and show us the game and your studio. It's very much appreciated. Could you explain the rationale behind releasing GT5: Prologue before releasing the full Gran Turismo 5?
So there's basically two reasons behind GT5 Prologue. First one being, as we move with the franchise to a new generation of hardware, the PS3‚ and trying to extract the maximum out of it and being comfortable, it's already taken us three years to get to a point where we're almost happy with what we're delivering on the system.
But we thought it's about time we release something on our franchise. We thought if we waited until the full numbered series product is out, number one we'd keep our customers waiting too long and we wanted to keep people aware we're still around, and keep GT in people's minds. So that's the more obvious reason. The second reason kind of relates to the first one; if we waited for GT5 with the online elements that we're talking about, such as GTTV or whether it's the online dealership concept or given the basic racing head to head online capabilities, we wanted to keep those experiments to a rather smaller compact designed game and be able to experiment on a base that is small rather than having a humongous base to start with and for us to be for the first time bringing the online elements to the franchise with the scale of a huge mothership so to say.

Speaking of GTTV, you've just said that GT5 has taken so long to develop, are you worried that things like licensing complications could further delay the actual, final product?
Looking at the angle of our relationship with car manufacturers and licensing that surrounds those, luckily we have a history of ten years in our franchise and we've managed to establish a very good relationship with all if not most of those parties. so that really isn't affected in any way. So that's one thing. The other angle surrounding GTTV, again a lot of the content really doesn't have a deadline or an airing date that needs to be hit, so it's just a matter of us clearing the rights for the content and whatever is cleared first will appear within the window of GTTV and we can add and expand on that.

Just yesterday at the keynote they announced the rumble controller. Is that something you guys have known about for awhile? Is it being built into GT5 Prologue?
Yes, we did know about the new DualShock 3 controller. In fact, we were part of the evaluation process here at PDi and, for obvious reasons, we've always historically supported DualShock controllers since the first generation and we will support DualShock 3 with GT5: Prologue.
How about things like SixAxis controls? Have you thought about implementing motion controls into the game?
Obviously, yes, there is a feature set of the SixAxis but we do not plan to implement that in using it to control the car, the actual car in the race, but we have studied the characteristics of the controller, we have experimented with it and the GTHD free download that we started last year. We implemented one feature which was, if the person puts the controller down, the user interface will disappear, and if they pick it up it will appear back. Features like that we plan on implementing in GT5: Prologue. We feel like that is a good match.
You've obviously been more than busy with GT5 over the years. A couple years back there was an announcement of Gran Turismo for PSP and we haven't heard much about it since then. Has that been put on hold for GT5, or are you still actively pursuing it? Sometime in the future or not at all?This is still in the works, so we are still working on it, but this will be after GT5 on PS3. Because of the interaction of the PS3 – well, it's not that easy to develop on PS3 – we've had to put it aside a little bit, yes. But once we get GT5 out we hope to position it as the satellite to GT5 on PS3, GT on PSP.
Interactivity between PSP and PS3. One of the examples they showed at E3 two years ago was the idea of a rear-view mirror in a racing game ...
*laughs*
... so that example probably not being the best application of the PSP, have you considered any other kind of PSP interactivity with the PS3 and GT5?
Well, one example would be for people to utilize replays of their race experience. Take that outside the home, whereas at home you would need the PS3, but they can take that away and share. Another would be – and we would need to do further research, we're just talking ideals here – but it would be nice if we were able to allow people to compete whether they're on the road or in their living room on the PS3, compete in the same race. Even though the visual qualities will be different depending on which hardware they're on it would be nice if we could allow for that. Technically, we think we should be able to. Or another would be – a feature we had on GT4 B-spec – which is basically you're the race manager. You don't even need to steer the controller, you just set the car and let it go; you're managing it. Another example would be the PSP would be your management tool: give it input and give it instructions and the car would continue on with the race.
So the game runs at 1080p, 60 frames per second. That's something that, even on PS3, a lot of games haven't been able to accomplish. How much of a development concern was that when you were building it? How much time did it take to get the engine – which looks great running at that resolution – up to snuff?
First of all, Kazunori insists that a racing game runs at 60 frames per second. That's a must have from his point-of-view. And the characteristics of racing, or racing games, is that you're most of the time driving at high speeds. At high speeds, your view points are in the distance. You need detail, even for distant images, and 1080p was the only resolution that he could possibly think of. Both 60fps and 1080p were both must haves for the GT experience to be the GT experience. They've done some experiments on 720p to see if they could find a compromise but the minute they saw it, it was out the door.
So that's GT5. Gran Turismo PSP we already discussed. What's next after that? More Gran Turismo games?
Kazunori always wanted to do something beyond Gran Turismo, but with the PS3 and all the downloadable possibilities, that dream is further and further away. *laughs*
Thank you so much for your time!

Shut up and make with the Top Gear!
FOXHOUND @ Oct 24th 2007 3:41PM
I'd have to agree with Robot Devil there. I like playing DIRT and even PGR... but GT5 is really all I'd like to have. And yet, they keep "c-teasing"(c'mon, you know what I mean by *that*)...
I do like the idea of using the PSP as a race manager or on-the-go racer when away from the PS3. As for SIXAXIS controlling the cars... thank heaven that idea(along with the PSP rearview mirror)idea has been pushed aside for the most part. Not even the Wii controls in that aspect have been solid enough for that... as much fun as EXCITETRUCK was, it still needed another good month of tweaking.
DoggySpew @ Oct 24th 2007 3:41PM
Great interview, but I am a bit dissappointed for not asking the question wether or not damage will appear in GT5.
Shagittarius @ Oct 24th 2007 3:47PM
I think they already said no damage modeling in GT5.
Anonim @ Oct 24th 2007 10:24PM
They didn't asked about upscaling from 1280x1080 to 1920x1080 also....
"how they reached the elusive 1080p goal" - like The Darkness and Ninja Gaiden Sigma by upscaling and added: turning off v-synch - how I love tearing of screen! and making 2D trees and 2D spectators.
FOXHOUND @ Oct 24th 2007 3:44PM
Purely speculation here, but I'm thinking there's no collision damage other than possible "dirt on the car, requiring a wash"(if they even bother with that feature). OEMs are so hesistant to see their work get busted up in videogames, especially if the damage rating on the car is piss-poor... word'll get around even faster about their safety ratings.
...And there have been numerous interviews & videoes about GT5 that don't seem to ask/answer/show damage to the vehicles. :\
Jnas @ Oct 24th 2007 3:53PM
Right now theres no way of looking around the inside of the car! (I have the JPN demo), so i'm thinking they could use the six-axis to look around.
Vidikron (FU) @ Oct 24th 2007 4:49PM
That's a good idea. I have the demo too and I noticed that you couldn't look around. PGR4 has the ability to free look inside the car and it's a nice feature. I especially like it during the replay since you can free look around the car while the replay is going.
Tim @ Oct 24th 2007 7:51PM
Actually you can, i use the driving force wheel to play the demo and using the dpad on the wheel you can look in five directions, i know this doesn't work with the standard controler, but you don't have a spare finger anyway
Mr Khan @ Oct 24th 2007 4:41PM
Ahh Polyphony, they're the Miyamato of Sony
I'll leave others to interpret this their own way
thomashenwood @ Oct 24th 2007 5:41PM
It must be 1080p... because LOADS of people own a 1080p TV :D
Si @ Oct 24th 2007 7:24PM
FFS, stop crying that YOU don't and get get a better job.
gonk @ Oct 24th 2007 6:17PM
why do people care about GT so much? I can't tell the different between any car games, myself
OzyDave @ Oct 25th 2007 8:25PM
Why are you reading this then?
AaronMD @ Oct 24th 2007 8:04PM
I think its silly that developers don't make motion control optional. Motion control could be a fun addition to this game if made available as an option. On the flip side, Lair may have gotten better reviews if motion control was an option.
I myself modified an xbox 360 controller to have motion sensing just for use in Forza 2, and I enjoy playing it more now.
gonk @ Oct 24th 2007 11:40PM
i read that sony made it a requirement, like how 360 games need achievements
mj @ Oct 24th 2007 8:35PM
So it's not worth playing if I have a 720p TV?
I played for years, but I'm done with GT. It's been too long and they aren't that realistic compared to the pc games. When they announced the ps3 at $600, that was the last straw. By the time GT5 is ready and Sony figures out what they're doing online, we'll have another xbox.
OzyDave @ Oct 25th 2007 8:25PM
They didn't asked about upscaling from 1280x1080 to 1920x1080 also....
It is already 1920 x 1080 to run at 16:9 ratio. Also if something is 1080, then you can't upscale to 1080.
