This game doesn't have a lot other than excessive and unoptimized graphics, while the driving does have a fair bit of depth...it's simply not interesting or relaxing.
For one, Drifting (which is a weird thing to put in a relaxing car sim), feels awful and more like your car is possessed by apparition than adhering to the laws of physics or enjoyment.
For a relaxing car sim, there's not that whole lot to relax to...at least within the demo levels, You can't exactly chill because there's still quite a lot of effort to go through when controlling your car, or else you'll be at a blistering 40 and bored out of your mind.
Maybe the city stages are better at this, but the long highway stage is just boring, I'd expect to be mesmerized or immersed to truly groove with it...but the game is simply not that enjoyable in my opinion.
And when it's not trying to be relaxing and instead exciting, it fails at this too, the controls are stiff and overtaking is too easy since all the AI are matching the speed of smell.
There's simply not enough going on for enjoyment of both types.
Personally, I sense that there's been more focus on form than function, and the game fails to be exciting or relaxing...it still earns a 4/5 because of its effort and relative polish.
Best of luck, Vitaminsiz! cheers.
