Cars and Tracks In this department, none of the games are really lacking, although some may have more content than others. Starting with Forza Horizon 3, it has no real circuits, but the open road through the Australian outback is vast and you can also go off-road.
I want them all.
Forza Horizon 3 all the way .
Assetto Corsa has the most advanced driving physics of the lot. But it doesn't seem very fun to me. Neither does Project Cars. Feels soulless somehow.
FH3 would be a given if I owned an XB1. As a Ps4 owner I really hope GT Sport delivers, although I have my doubts. The driving physics and audio have been falling behind in the past releases, with the cars feeling stiff and robotic. They need to make it feel more alive.
