Wow I didn't realize that wold be so fun! Thought it would be impossible to decide between all those courses and cars but those are the ones that came to mind.
I tried to find really hard combos that would really give the driver a test while at the same time making it enjoyable. Only the best for the best!
I pretty much prefer arcade mode, time trial/hot lap races over multiple lap races.
PS: Are we allowed to suggest N1-3 tires as well instead of only sports?
