Counting different layouts , changeable weather , Kart tracks ,dirt tracks could have that number only through updates at the future .
What is needed is to have more original tracks but i guess they must pay the " right" for that .
With track path editor at gt6 they " skip" ( short of ) this problem but its not the same.
They are many tracks around the world and historic ones ,leaving aside some of the " boring " designs of Herman Tilke the last decades deffinetly they can bring some of them at the game.
But except the development they must also ...... pay the ferryman .
Still all these years , they use the name Cote d' Azur instead of Monaco or Monte Carlo and it's not accidental.
