To begin with, I will write a list of Grands Prix that I would like to see in the game: Toscana, Zandvoort, Magny-Cours, Jaypee Group, Hockenheimring, Enzo e Dino Ferrari, Brands Hatch, Algarve, Ha Noi, Indianapolis, Nurburgring( Northern ring), Bahrain ( Rolex Sakhir).
The list of routes may seem strange. In my opinion adding short and very long runs to the game will add more
The game has two similar versions of the Silverstone track, to make the difference between them, you can add an additional DRS zone. In some other routes, it is probably worth making 2-3 DRS zones.
The characteristics of the car are divided into priority and secondary, and improvement occurs according to one scenario. I suggest increasing the importance of the cooling feature. To do this, you can add a function to limit the engines used in the season in the League editor menu.
For the interest of the game and the development of new tactics, I suggest adding the function of disabling refueling in the menu of the League editor. This feature will increase the importance of the car's tire and fuel economy characteristics.
