I'm definitely sorry you feel this way. Honestly, I felt that The Crews car turning was more of GTA's than a true car game but I did enjoy what it offered.
There definitely have been some disappointments with Payback, but the story is massively better than NFS2015, the gameplay is nicer with a day-night cycle and rewards from free roam activities, and the car physics is better in my eyes (because you can rely on your car doing what it should when it should do it), along with a better selection of cars this time around. I, personally, have enjoyed the heck out of this game, so I am sorry to hear you aren't able to say the same. Where did Payback fall below your expectations?
