Bought the game two nights ago. I'm in love with the new physics.
Old habits die hard so the first thing I did was blast through the license tests, watched the racing etiquette workshop (which could've been worded better or phrased in a more mature way; it sounded too childish) and hopped in an online lobby.
First thing I did was select Suzuka East Course, and hopped into a drift lobby. Players were understanding and helpful in regards to tuning and to controller setups, etc. Had a lot of fun!
I love the new indicator system. I can finally enjoy track days without the constant blaring of the horn or misunderstanding where to pass a slower car.
My biggest gripe currently is the lack of an FOV adjustment or interior camera adjustment for specific vehicles. The Mustang interior is way too close to the point where I can't even see my mirrors.
I have yet to experience the headache of ranked gameplay, I might never even try. It's hard to be competitive with a controller but I'm getting used to controlling the car with the new physics. Not saying I'm the fastest and most experienced driver but for having only played two nights, I could hang with most drivers on the Nürburgring (that's my personal evaluation of my skill-level).
For once the physics feel... intuitive. I don't feel that there is a huge learning curve. The throttle can be finicky with a controller. I have to use my analog sticks for the throttle because my R2 button currently emits only 50% throttle, so I'm fine with binding the L2/R2 buttons for shifting. Drifting was intuitive, I could actually tell when the car was on the verge of spinning out and I could feel the right moment to engage the throttle in a transition curve. It feels amazing, to just have the ability to get in and feel one with the vehicle.
I'm sure on a wheel and pedal setup with the right FFB settings it would greatly enhance the experience but they have nailed the visual, physical, and audio cues overall.
Feels good to be back in the proverbial seat.
Will try my best too!
