So this thread has made for a long read. I might as well add my thoughts and opinions. This is all based on about 7 hours of play so far.
And sorry this is probably going to get long winded.
FFB - So ffb is very subjective. Everyone has their own prefence's as to how they like the ffb to feel, so I'm not going to say here that it's the best ever. However I feel it is vastly improved over PC1. Much simpler to set up and out of the box much better feeling, though there were some issues. I could not get good bump/curb feeling on my thrustmaster Tx, so I am using Jack Spades files and they have greatly improved that aspect. And ya I had to tinker and adjust to get it feeling the way I like, but I don't get the complaints about this, as in my experience every sim needs some adjusting, depending on wheel and preferences.
Physics - Again I find this highly improved. I'm not a race car driver, so I can't comment on how realistic this game is or is not. However I always felt with PC1, that the cars felt like they were floating. It just never felt like they were attached to the road. Though some of the cars vary on quality, as a whole I definitely feel more connected to the road . Upon reading many threads on multiple forums, I have found people complaining that the cars have too much grip, and I have seen people complain the cars spin to easily. So far in my experience I would say the cars feel like they have more grip then most other sims. I have not had the problem with uncontrollable cars. My only experience in a race car, was being taken around for a few laps at Mosport, in a Porsche cup car. I was amazed at the spied we took corners at, and how planted the car felt along the way. Based on that experience I would not say PC2 has too much grip. The car will still spin when I obviously push it to far, or at times when I clip a curb at the wrong angle and speed. But when I do spin it makes sense to me why it happened. I have yet to have an incident that just left me wondering what just happened. Not saying that doesn't happen, I just haven't experienced it yet. Now all that said is the physics perfect? No. I probably prefer raceroom at the moment. But they aren't trash like some say. I'm opinion the cars mostly feel good and are fun to drive.
AI - So there are definite problems with the AI. I have yet to do much racing with the AI, but definitely slow corners and closely pack cars are an issue. Hopefully they are able to fix some of the AI issues through patches, though for me personally I don't spend a whole lot of time racing AI, so it's isn't as big of a deal to me as it is others, but I see the issues there if that's your main thing.
Multiplayer - So their new ranking system is a nice step in the right direction. Over time as players get into their proper ranking level it should be able to set up some good races. I just wish they had gone all the way and put in iracing style series with different rating restrictions, and scheduled races etc. Just having people set up a bunch of random servers can be some fun, but I personally like the more structured approach.
Single player - So assuming the AI gets worked out to a more acceptable level, the career mode still doesn't interest me that much. I did t enjoy it in the first one, and it seems more the same in this one. It would be nice to at least be able to set up custom championships. It is coming to multiplayer, so i cant see why it would be to difficult to add to single player as well. I do enjoy the hot lap competitions. Those suck me in on any game that has them. Hopefully one day I'll get my dream of a real sim getting a real career mode like the old EA NASCAR games had, where you worked your way up from the bottom, earned sponsors, made money and eventually could own your own team, hire drivers get sponsors etc.
Bugs - So I know many of you have likely logged more hours then I have, but I have yet to encounter any of these game breaking bugs that have been written about. With so many variables I systems, and circumstances in a race, I'm sure there will be plenty of bugs people come across that I never do. But so far in my experience it has been fairly minimal, and even though it kind of sucks, these days every game, including sims, will have bugs when they ship. It is just reality of games now, and I am used to it. As long as the developer works to fix the issues as quick as possible, I'm used to it and can deal with it.
Misc - So one thing I have seen posted multiple times, and it is driving me crazy, is that this is just PC 1.5. If this is your feeling can you explain what you feel should be in a sequel? PC2 includes more cars, more tracks (many of which are laser or from scanned), better physics, better ffb, better multiplayer system, improved weather, and more. What is it that would need to be included to make it a real sequel?
And I just can't see where some people are just saying this is simcade or comparing it to Forza. This is a sim. It might not be exactly to your liking, but they are definitely striving for realism.
Another company I have seen but don't understand is that 2 years after the first one we now have to shell out for PC2, and they will likely soon be working on PC3. I know most if not all the current sims are working on a service model, compared to a traditional sequel type model, however I don't see what the complaints are about. Raceroom is my current go to sim, and before that Iracing. Sure you don't have to worry about buy a sequel every 2-3 years, but I guarantee I will have spent more on their content in 2 years then what it cost to buy the new PC.
It seems like this game is getting A lot of negativity due to the first one, and that they dare release on consoles as well. I get the disappointment in PC1, I was highly dissapointed in it as well. And I get a lot of people didn't like how SMS leadership dealt with people and game issues. However based on playing PC2 on its own merit, and leaving everything else aside, this game is much improved. I get that it is not perfect by any means, and not everyone will like It, because there is no product that everyone likes. But I find to many one line posts on it being garbage, with no elaboration, that comes off as just wanting to bash it because it is a project cars game. I find that very dismissive of the work they have put into it, and the positive steps forward they have made. I'm the end we should all hope all these sims are good, and keep driving the others to be better. But for this one it definitely seems there is a chuck of people that just want it to fail no matter what.
