Track selection is poor, Project CARS 2 with a smaller budget did better than the XB1 FM's in that regard and this is a further step back, no Nurburgring at launch for the first time ever in a FM game as well.
I guess you've just got to hope that the new upcoming tracks are released before you get bored with those in the initial release, however, if the physics are good, and can very rarely get bored, especially as all the tracks have dynamic ToD and weather.
FWIW, PC2 was a terrible, terrible game!.
