You're going too far with that virtual virtual world. If you want to do that, any sim can have anything. Flying cars, power ups, what have you. Anything is allowed. I don't think we should be headed that way.
You're partially correct. Virtual Virtual world allows anything to happen in a sim, but you would only really add things that would satisfy the consumer/appeal to the game's identity. Rewind can help you learn so it gets in. Nothing's stopping you from putting machine guns on a real car (I guess, though you might find it hard to enter a race) but they wouldn't help you learn to drive, so they'd get axed.
And if guns were added, so long as I could turn them off it would be as if they were never there and I’d have a fine sim.
If you want to go in depth, all simulations are limited. Simulations can only be limited. A computer can only replicate partially what happens in the real world. No matter how powerful it may be. Even if a computer one day is able to simulate every single atom and its subatomic particles, it still would need to replicate infinitely small time steps. There are infinite steps to reproduce between 0 and 1 seconds, what requires infinite processing power, what is impossible.
Limitation, approximation, is something intrinsic of a simulation and part of it's definition. If not, simulating would not be possible. Therefore, a simulation must be valid even if limited. Using your own example: "We will use a smoke machine to simulate the fog you will actually encounter". A fog machine replicates "the fog you will actually encounter" exactly? No, but it's a close representation of it. It's a believable representation of it. It serves the purpose even though it's limited. Therefore, if a simulation lacks something, it's still a simulation. That's why it can lack damage and have a more simplistic physics but still be a simulation.
Very true, sims are only models and not reality, but nothing was stopping damage from being in GT3, 4, and 5P given that it was in GT2 and in comparable games like Forza. It was no hardware limitation unless PS2 and 3 and/or PD's coding is just that bad.
Stnd physics doesn't have an excuse either so long as GT is striving for ultra realisticness that blatantly ignores anything that can't happen in a real car. It's not a limitation, because pro physics is there. It's an option to lower the realisticness of the game to make it easier and nothing more. That's the entire admitted point of stnd physics.
Luckily, stnd physics is optional so it doesn’t void the sim. Damage is in GT5, perhaps optional, so it doesn’t void the sim. Adding these things as options just lets you tailor your sim, how approximate do you want it or need to be at some moment?
By the way, the plank time is the smallest unit of time. About 10^-44 seconds.
However, if a simulation adds something that has nothing to do with what it is simulating it can't be a simulation anymore. Let's say we add a flying car to the smoke of that fog machine. Is it a valid simulation now? It could be, but see below.
Well, if the car has wings and jet engines, it could be realistic. But you're probably talking about it flying by some magic force. This has nothing to do with driving or training or racing so it can't really be justified. Rewind on the other hand isn't meant to be a part of driving, it's for training. A simulation does not have to be completely faithful to reality in every way. In GT, the physics should ideally mimic the physics of real life, after that you're open to do whatever. If you wanted to simulate a race, don't use rewind. If you want to practice, you can use rewind.
Using rewind does not void the sim, it's merely a feature of the game. It's a matter of what is being simulated. If GT was labeled as a racing simulator with the express purpose of only simulating a race as it would be in real life, ditch rewind. The game would be less interested (perhaps not interested) in developing people's skills and more interested in forcing immersion (I used the word "forcing" instead of "creating" because the lack of rewind does not create more immersion/realism, it's up to the player to use rewind or not).
And by your definition (adding = not sim) GT is not a sim because of stnd physics.
I don't like those sorts of stupid exaggerated comparisons but:
Following your logic, I tell you GT should have power ups. You know, machine guns, bananas, red shells, all of it. You can turn it off in the options, so it's not forced. It doesn't violate the simulation.
Would be a stupid feature, wouldn't it? Why? What the hell power ups have to do with real driving? What the hell rewind has to do with real driving? What the hell a flying car is doing in a fog simulation?
Well if I could turn it off, I wouldn't mind. And yes those things (besides rewind) would be stupid. But rewind wouldn't be because it's a training tool. And on top of that, since those crazy things aren't forced, they don't void the simulation. If GT5 turned out to be GT+Mario Kart options, I'd simply turn off the MK options and I'd have a fine sim. Likewise if you want to simulate a race in GT, don't use rewind. If you are just simulating driving, go ahead and use rewind. All rewind is doing is letting you choose where you’re driving. Of course, you claim rewind doesn't happen when driving, and this is true. However that is understood within the game, rewind would not be there to enhance the realism, it would simply be an option to let you control your sim experience. In this way, it is much like restart or a track section select, or something letting you tune your car while driving. Adding something does not necessarily void a sim, it just simply allows the sim to do something other than solely replicate reality. I'm using CAD to design some stuff. When I want to see how it's going to break, the program run a simulation, colors the part according to what deforms the most, greatly exaggerates the deformed shape, and gives me all kinds of readouts of stress and whatever. I wouldn't get that bending a real piece of metal, but it doesn't subtract form the simulation, which in that case was accurate and had stuff added to it from information purposes. Rewind in GT would be added for training purposes. Flying smoke machines wouldn’t really serve any purpose, they’re not like rewind at all.
But again (and actually as you said in the above quote) it's about what makes sense in the game. Power ups don't, people won't benefit from them in terms of increasing driving skill. Rewind can benefit people.
I stand by my point. You're not only misunderstanding me, you're also misunderstanding Gran Turismo. Gran Turismo's goal is to deliver a real driving simulator. If it has nothing to do with real driving, it should not be in the simulator. Power ups, rewind or flying cars alike. They are so out of context, that you just can't call the game a simulator anymore if it includes any of those things. I doesn't represent what you would expect of a driving simulator. Therefore it's not a simulator anymore.
And rewind is not in anyway against the style of a real driving simulator. It doesn't represent what
you expect, but it makes plenty of sense to me and a few others. You can't rewind in a real race, fair. But you can't rewind online.
What about offline races? The player is free to do as he pleases. If he's running the 24 hr of LeMans as a practice, let him rewind as much as he wants. But the "Any way to play that does not meet my approval" crowd will have a problem with this. So if rewind were limited to practice (which is not necessary since the proper way to play single player is to do whatever you want no matter how insanely ridiculous) you couldn't complain at all.
And if GT is meant to train people (which it could be at the same time as being a driving simulator) there is no reason to leave out a training tool.
I can picture a lot of people going "What the hell? Why can I rewind the race? What is has to do with real driving?" if it is included in the game, can't you?
Only if they are irrational and don’t understand what a sim is. If they use logic and reason they wouldn’t be bothered because they can simply not use rewind when they feel it would invade on realism, which is only when you are trying to simulate a race. At other times, like training, rewind does not add anything that would lessen the experience. It only gives you the means to tailor the sim to your needs.
