John Doe medal 5092 6 years 134 days ago
I would like to suggest that the igp manager put more circuits in the calendar and not only that they are part of Formula 1, but some historical and legendary ones like: Le Mans, Nurburgring (100%) and Indianapolis Motor Speedway.
Skull Racer medal 5000 6 years 134 days ago
Add to the list:
Estoril
Brands Hatch
Donington
Red Bull Ring
Nurburgring Nordschleife
Gerard VC I medal 5719 6 years 133 days ago
Add also:
Watkins Glen
Gilles Villeneuve (Canada)
Austin
A. Hermanos Rodriguez
Baku
Dick Wolff medal 5000 6 years 130 days ago
Maybe also generate random race calendars, so you don't always have the same races.
