I loved the game, but it moves more like Minecraft than Gran Turismo. You have to make your own fun, give yourself your own goals, and try to make the best of it. Besides the very bare minimum required to get the credits to roll, there's really not much of anything to progress towards considering you can buy nearly everything right away and money is easy to get (especially with the economy being broken the first month with HE cards selling for absurd amounts). Perks really don't do much of anything other than give you some easy money at the start if you fill up that tree. Winning races is sorta trivial and doesn't really reward you.
The strength of the game is that it feels to me like the aftermath of regular Forza or Gran Turismo. You beat the game, you've clearly proven you're the best driver in the world, you have a gazillion dollars and cars, and this is the epilogue. You are just traveling the world doing whatever the hell you want driving whatever you want because you can. Nobody stops you because your a god amongst men.
The weakness of the game is the difficulty in balancing challenge per race. Some races are actually challenging, most races are pathetically easy even if you crank up the difficulty. Even then, a lot of difficulty comes artificially by just not knowing where to go when you're driving offroad in fields and forests. Add in blueprinting, and I honestly felt more like I was playing "RaceMaker 3.0" at times rather than a pre-made game.
Overall, I had a good time with it, but it's really flawed, and that doesn't even touch on the horrendous technical problems or bad game design decisions like constant mini transition demos that can't be skipped or the nagging NPC event organizers stealing your screen from you to show you shit you don't care about.
I was using DSR on a 2500/970 to do 4k and I got a strong 30 with most settings still pretty high. 60 should be possible on those rigs. This game plays well when it's abusing your hardware as it nullifies the stutter problems.
