Fuck Ubisoft.
If you want a good open world racing game, well Motor Town: Behind The Wheel isn’t strictly a racing game… nor technically even focused on being a racing game, it is an open world driving job simulator and there are lots of sports cars and you can do lots of jobs where you are racing against a clock.
There is also multiplayer and a custom race system (as well as actual race tracks interspersed in the world).
The reason I really recommend it though is the driving feels better then just about any other game I have ever played, especially tire grip modelling. I don’t know how to describe it other than it makes me uninterested in driving cars in most other games lol.

That is exactly why I also buy things on Good Old Games and also play open source games like Beyond All Reason, Xonotic, Cataclysm Dark Days Ahead, Luanti and other games like Vintage Story that I can purchase from itch or directly from the developer and install directly on my computer as well!
