Overall, I'd say this is a pretty good version of NW that you can definitely have fun with, but it does have its ups and downs.
Purely as a track - with AI not factored in - this is where this mod shines. The bumps and the way the track drives overall both feel highly realistic, and it's so fun testing and tweaking setups to try to get the most out of the car. (Protip: soft right-side suspension works wonders with the HSS 1994 Stock Car mod).
Where it falls apart a bit is with AI. For some reason, about half the AIs don't want to move on the first attempt after loading in, so you have to restart the race to get them to move. And even when they get moving, they're honestly nothing special. They crash often, which causes huge pileups, and even their fastest laps are around a second off what a human can do - quite a difference over a nineteen-to-twenty-second lap and often difficult to navigate due to the huge speed differences.
Rated 4/5 because it's definitely above average, but the AI really needs work.
