My criteria for judging a sim vs an arcade comes down to how the car handles to me. I don't really care about laser scanned tracks and pit lane features and etc.... Without going into a long post, I'll put it like this, Horizons 2 is arcade to me...the cars are numb and super easy to do whatever in. Whether you use a wheel or controller, you will find that you can be a driving god with very little input. On the other end of the spectrum (for me) is rFactor2. The cars are very communicative, my wheel responds the same way it does in a real car and the physics mimic what would happen in real life. Both are fun but in very different ways.
Project CARS is right in the middle for me.....where it does take some skill to keep the cars under control, they also seem easier to control than other sims...A/C, r3e and rF2. I find myself catching slides that I know I wouldn't be able to in other sims, let alone, real life. In A/C, when I go into a turn, I can feel weight transfer as my wheel loads up and gets a little stiff, then the stiffness lessons as the car rotates, then it disappears once the car is straight again. PCARS has none of that. I also can feel camber changes in the roads in other sims, not just bumps, but my wheel will pull to whatever angle the road is cambered on. I get none of that in PCARS. Yes, I can feel some bumps, take Monza or Satikko for example, but I never get a feeling like my car is skipping across the surface, which is what would happen in real life when taking a bumpy curve.
Damn, this post was longer than I intended, my bad. For me it's all about feeling and physics...can I feel what the car is doing and how the road feels. I think most would agree that Iracing is certainly a sim but in my opinion, the driving dynamics are, shall we say confusing to me. In Iracing, I feel like I'm driving to accommodate Iracings physics as opposed to driving the car all out like I would in rF2 or A/C.
A favorite test of mine is to pick a car and track that is in all or most of my sims and drive it back to back in each sim. Any of the Nurburgring courses are good or Monza as they all are bumpy and have camber and off camber turns. Decide for yourself which car communicates when you test...can you tell/fee when the car is understeering or oversteering? Can you tell when you've loaded up the outside tire and need to back off or adjust your steering input? If you're in a high speed sweeper, can you feel the car go light if there is an elevation change? Being that we don't have the benefit of g forces in sim racing, I for one, need all the feedback I can get. BUT, I have buddies that don't require that. They have the ability to eyeball everything so FFB and physics aren't as important as they are to me. They're also very good with controllers so take that for what it's worth.
But let me be very clear, THIS IS JUST MY OPINION, so don't flame me bro.
I am by no means a fast guy. I drive more for the challenge and enjoyment than lap times and victories. There is no right or wrong in this topic. With all of my sims, there are things that each one does better than the other. I love them all individually for their specific traits. But purely in terms of driving pleasure, devoid of graphics and sounds, PCARS (and Iracing for that matter) is lower on my scale. But when I factor in the "theater" of PCARS or the online community in Iracing, they quickly gain points as overall enjoyable experiences.
Again, sorry to be so long winded.
