Comparing to a decade ago, there's an absolute wealth of racing sims out there, with something for everyone.
I remember falling in love with racing sims because of Forza 2 and Race Pro, both on Xbox 360. But on PC, when it came to racing sims there was either the draconic iRacing, early in its development, or Race07, which was also draconic and technically outdated upon release. Oh and, without a racing wheel, you were essentially stuck with Need for Speed: Blegh.
Since then, the Xbox 360 gamepad really popularized gamepads on PC, and there's been a tremendous uptake of racing sims on PC of various calibers. Project CARS is on its second sequel already offering something similar to Forza and Gran Turismo, some Forza games are even available on PC, Assetto Corsa and Competizione offer Italian flair, rFactor 2 and iRacing have continued to grow, F1 2010 resulted in a solid F1 racing game for ten years going now, RaceRoom Racing Experience has that f2p draw, there's MotoGP 13-20 and Ride 1/2/3/4 for people who don't like training wheels, there's Dirt and Wreckfest and Automobilista and everything else out there.
I really feel there was a time when proper racing on PC was either extremely hard to get into, or extremely hard to find, and now we're spoilt for choice. There's something out there for everyone, and I really, really wouldn't want to have it any other way.
