These days I play a lot of Forza Horizon 4 and not much else, since I haven’t found anything else to really click. There’s a couple good ones out there though: Motor Town is pretty good as a car game in general, not just racing. Also BeamNg if you just wanna fuck around with the physics engine. Ooh, and Dakar Desert Rally is a fantastic rally raid simulation (albeit somewhat flawed)

Otherwise I would give some classics a shout: GRID the original, still holds up today. Also NFS Porsche, which was so ahead of its time it’s ridiculous.
