Being wistful about older sims lasts until you go back and actually try one. Modern FFB together with laser scanned tracks so totally blows away anything from past eras.
After AC came out, I tried Race07 once then uninstalled it. It felt so crude in comparison.
Actually, as I've said in another thread, I only started serious PC sim racing 2 years ago. So the memories of those games are still fresh in my mind. In fact, I still jump on GTR2, LFS, RBR and GSCE (which is basically an rF1 mod) every now and then. I got AC a month ago and I have been comparing physics & FFB back & forth.
Race07 is an anomaly. Even though it still uses ISImotor, Simbin made a lot of changes to make it more accessible than previous offerings. I'm not surprised you uninstalled it, I couldn't stand it myself.
If you don't mind the graphics, I would highly recommend Automobilista (a repackaged GSCE, which means it's rFactor "Perfect Edition" basically) and give it a good comparison with AC. I think you will find it's not as clear cut which is better 👍
ISImotor FFB (with RealFeel) is very crisp and gives you a good feeling of the limits of grip. Weight transfer and oversteer detail is lacking though. AC FFB is mushy and it's hard to feel the limits of grip, but gives good weight transfer info. Road detail is amazing as you said, but that's more due to laser scanning than the actual FFB. On mod tracks without laser scan it feels so-so. Neither feels 100% right IMO. A mix between the 2 would be much closer to reality.
I should also state that my G25 wheel is probably able to use 100% of ISI FFB, but not 100% of AC FFB. If I get a T300 in the future I wonder if my assessment will be different.
The core team at Kunos is 10 people. 10. People have awfully high expectations of 10 guys.
You only need 1 guy for physics though. Even Gran Turismo only have 1 guy for the physics of 1200 cars (Akihiko Tan). My original issue of missing brake temp simulation can certainly be done by one person.
The large number of developers in T10/PD is dedicated to modelling cars/tracks. Which shows in AC's car/track count. Not that I am complaining since they have done an incredible job with the number of people they have (and mods fill in the gaps anyway).
At the end of the day, it's also not the number of devs you have, but the philosophy of the lead game designer. If AC doesn't consider brake temps important then we're not gonna see it (which is a shame). Same with PD, if they don't consider good engine sounds important, we're not gonna have it no matter how many sound engineers they hire.
I don't really understand all the negativity surrounding 'the current state of sim racing', if you come from console racing games the complexity of these games, their physics and the ability to customize every aspect really does feel like the next step with regards to simulation. And most of it created with far smaller budgets.
Sure these older games might have had a couple of features that are now lacking, but it works both ways as current games have features that were missing back then. In the end every game/dev will do things differently.
Comparing to console there's a clear winner, but comparing to older sims things aren't so clear cut. In my mind progress always includes everything that comes before it. If you pare down graphics and laser scanned tracks, there's actually not much that AC does better than older sims.
Games like GTR2 just feel like a complete package out of the box for me. Everything is self inclusive. AC feels like a perpetual science project. Sure the physics is more complicated but you'd expect them to at least start on the same level as the previous generation in terms of things simulated. As I said above, it seems to be a philosophical issue with the dev team though, not an ability issue. If that's the case then there's nothing we can do.
I don't know, the jump from GT to older sims feels BIGGER than the jump from older sims to newer sims. I was expecting to have a "Holy crap this is exactly what I feel when driving a car IRL" moment when playing AC for the first time, but it was more "Wow, laser scanned road feel is amazing, but umm... something still feels off".
I shall continue to have fun in AC, but sadly I would need to wait a bit longer for a true virtual driving nirvana
