I mean that has licensed tracks and cars that you can modify in stupid fun ways? The last time I played Gran Tuismo was on a PS3 and I played it so much.
I have purchased a few games over the years, Project cars 1-3, Asetto corsa, Forza Horizon, The Crew 2… all of them were interesting in some ways, but I just miss grabbing a boring car and modding it to stupid power levels and racing it at Laguna seca for example.
I’m not really plugged into the racing scene but my buddy suggested Wreckfest. As they have workshop support, so someone may have made the tracks you’re hoping for.
