Not a big fan of ovals, but I think there presence is important in the game, can provide very fun races, specially with tire wear and fuel consumption active.
Northern Island is replica of Bristol Motor Speedway, exactly the same size, and Nascar puts 40 cars racing on it two times every year. The problem is when you put fast cars and players SR B or lower...
Blue Moon is very fun to race in road legal cars, with road tires and lots of slipstream.
BB Speedway is just annoying.
The game lacks some faster ovals, like previous titles had Daytona, Indianapolis an Motegi, for more powerful cars.
Daytona is bloody fastest, Indianapolis is fast but is tricky with its relatively low camber corners, Motegi makes you use your brakes, added to Blue Moon and Northern Island, you would have the all around in oval tracks. I believe many people would enjoy it. Not being my cup of tea, I'm sure I would race it on Sport Mode. Motegi on a one make, road tires, Dodge Charger Hellcat would be a very enjoyable race, I believe.
On rally mode, PD never got it right on the physics side, maybe some people dig it, I don't know. IMHO PD should do it right or spent the time in more useful things, like improving the penalty system.
