*sigh*
Right there with you Mac K - this thread has gone off to become "The Scaff Show" - lets lock it up shall we? Obviously if you disagree with Scaff on the physics modeling between the two games, you're incorrect.
Nevermind the fact you seem to think you are the deciding voice on a thread's closure - there is a difference between people voicing their opinions, and stating these opinions as facts. This is a discussion about the physics engine, and yet people have (repeatedly) brought up Kaz's race-driver moonlighting as a supposedly valid point in GT5's favour, as just one example.
Shift 2 had numerous drivers' involved in its development - actual race drivers, too - does that make it a better simulation? Absolutely not. It's also very unlikely Kaz has as much of a hand in the direct workings of the physics engine as he did in previous installments - he is after all, a busy man.
So, I'll likely get banned for this post, but it needs to be said:
Nothing here states "having differing opinions to a member of staff" as an offence.
I've played both games, and whats been said about tire modeling is correct - but lets be clear here - FFB is what makes or breaks the driving experience - so if your talking about driving with a controller, I can't be bothered with that discussion - there's a reason drivers talk about "feel"; if you don't have it, you don't have confidence, and the driving suffers. The FFB engine in Forza 4 is far behind GT5, about as far as GT5 is from iRacing. No Scaff, I'm not Googling the articles for you to back up what I've said, as others do agree. No, I'm not digging out specific car examples. It is a blanket statement across both games, and MY OPINION ON THE MATTER. Others ALSO agree with me. Shocker.
Others also disagree. Hence this discussion. So, as you say, let's be clear here - GT5 is hailed as the best simulator on consoles on release, largely thanks to its physics engine, but now what really makes (or breaks) it is the FFB?
So Scaff, ban me if you must, but the only reason others haven't been all up in your grill about being combative and confrontational on this topic is PURELY because your a mod.
Good day, sir.
I'm not sure how long you've been reading up on these sorts of topics (the FM vs GT ones in general, or physics discussions with regards to GT and its competitors), but the reason some of us strive for so much empirical data regarding these things is that the vast majority of these discussions are utterly bereft of it. Sure, a lot of the pro-GT talk can be chalked up to this being, after all, a GT website, but the amount of people who will make baseless claims without so much as even playing Forza is depressing. Flip that idea on its head - imagine a new user (or even an experienced one) dropping in to mention their complete disapproval of GT's physics compared to... again, let's say Shift 2, despite
never playing GT. It would be laughable.
In your situation, you've played both, and that's great - but a lot of people haven't. It's much easier to come to conclusions without having to do the research to back them up. When people make these claims, in any game, I don't think it's unreasonable to ask for some evidence to support it. Heck, a quick browse over the last few pages lists criticisms levelled at Forza to be that it has both too much grip, and too little.
I can understand some diehard's opinions - I was skeptical of Forza for a long time. But I took a plunge, and I'm incredibly happy with it; I've grown out of the stage of thinking I have to choose one. These are games, they require no loyalty.
There is nothing wrong with people preferring GT5 (or Forza, or S2, or anything else), of course - nobody has said that, as preferences are inevitable. But tire physics, those can be given real weight, and show direct ties to the real world (as well as differences, since as mentioned, no sim is perfect). On the other hand, a single video, with no corroborating information about it, does not somehow "prove" a game is less realistic than another. There's an old infamous video of a car riding on top of another car around one of GT5's ovals, as just one example.
