The Aston Martin VGT trailer specifically mentioned how interior materials were chosen, and for the VW Supersport VGT the cockpit is pretty much provided by the Roadster. Same with the FT-1 VGT. Yet none have one. So it's a choice by PD as well.
How can you be sure that the VW Supersport VGT uses the same interior trim as the Roadster? Or that the FT-1 VGT has the same interior as the FT-1 road car? You're not the one who designed those cars. Because if that's the case, if it really is a choice by PD, then they should have slapped the RX-7 Spirit R's interior into the Bathurst R or Type RS or any other facelift RX-7 FD in the game. They should have done that, if it's just so simple. But it's not. You have to remember that these are
licensed cars being featured in the game. Car makers allow developers to use their cars in their games, provided they have rendered it as accurately as possible, according to the specifications the car makers have provided them. Because if they don't follow what the car makers want, they could get sued for it.
And for the Aston, maybe PD is saving up its interior trim for GT7. Who knows? Like I said earlier, it is not PD's job what kind of design or details goes into these cars. Their only job is to render said concept cars into however the designers want it to look like and appear in the game.
One more thing; if it really WAS a choice for PD for them to include interior details in these VGT cars, most likely they opted NOT to include them in GT6 because their staff is also busy working on GT7. PD doesn't have a huge staff (less than 200, AFAIK), and so compromises have to be made. They have to split their staff; some of them are still working on GT6 while the others are focused in GT7. I can only speculate that they are saving the interior details of these concept cars for GT7. HOPEFULLY this is true.
If these Vision GTs are driven at least once by pretty much all active players, that's already more usage than half the fully detailed Premiums in the game get.
Do you even have any idea how many Premium cars there are in the game? More than 400. The number of different JDM cars, American and European sports cars, not to mention race cars (GT3, SGT, LM) that I usually see being used by your typical active GT6 players already surpasses the current number of VGT cars available many times over. The only real time a VGT ever gets attention is when it's released; give it some 1-2 weeks and you'll see only a few people sticking to them. The rest are back to their own customized Premium cars drifting/racing/cruising/whatever. The only VGTs that last for quite some time are those that go Bugatti Veyron-fast, those few that can reach 200mph very easily like the Mazda LM55 and the Chaparral 2X. And you can expect the SRT Tomahawk to have the same treatment, because even though it doesn't have the handling to match its immense speed, it still goes crazy fast in a straight line.
Maybe people would show more interest in driving these cars if their interiors were as unique and interesting as the bodies.
Maybe. But remember what Kaz said earlier, he's not the one (or he's not the only person) who decides which car gets interior trims or whatnot. If the car maker has provided interior detail for their VGT, then cool! If not, then they just have to make do with whatever they have been given. And that's the thing with licensed cars in video games: whatever software you're using to render these vehicles, the car makers still have the final say on how they would appear in-game because they are the ones who own said cars, not the developers.
Sure, concepts are usually about exterior design, but real concepts often can't drive. Should we use that reason to remove the engine from all Vision GTs since some brands haven't provided a real powertrain?
That's just ridiculous to think of (dare I say stupid). If these designs weren't made to drive, then these should not have been provided to Kaz & PD. The biggest reason as to why these concept cars were provided engines/powerplants is because what is Kaz & PD are making is a
racing game, not an interactive car show. And so car makers have to come up with powertrains in order to allow them to move at least one centimeter on flat ground without the use of external force, in order for players of the game to actually use them. And again, it's just a concept; one reason could be that the designers aren't actually sure what kind of powerplant the car would have, or how said powerplant would actually work in real life (in the case of the Chaparral 2X).
Dude, seriously...
