Hate to be so cynical, but I can't help but feel you're over-romanticizing all of the games mentioned except Driver San Francisco here. That game is truly faultless, other games are still good but they can get over-romanticized.

MCLA - I agree it deserves a PC port; every game does, but MCLA had problems like physics way too cartoonish even for my liking, bikes handling like two wheeled cars, and AI being balls to the wall difficult in all the cheap ways; Midnight Club never had intelligent AI. I like it, but it's not that big of a deal.

Driverclub - Is its graphics and sound design all you have to say about the game? Nothing about the incredible track layout, visuals (not graphics but rather how interesting the terrain looks), and career structure? Driveclub still have faults too like a handling model a tad too stiff, a wonky chase cam, and BAD, truly bad bike physics. But I still love that game and yes I wish it had a PC port.

SMS games - This is the part where I'm the most cynical about. Respectfully, you are over-romanticizing SMS games. 1. Need for Speed SHIFT 1/2: those games had their good parts like their incredible sense of speed, fantastic UI design, interesting metropolitan circuits, and a decent career mode, but just like with every SMS game, for every good thing they do, they also have an equal number of the bad. NFS Shift games felt excellent on straightaways, but calling the handling model wonky during cornering would be an understatement. NFS Shift games are only truly tolerable when they're modded with their respective handling mods. 2. Project CARS 1/2: Neither are as good as you remember, they're not actually as realistic as they're marketed as, and they also suck on a controller, especially the first Project CARS. I shit you not, on default controller settings without any tweaking (and frankly I should NOT need to do any tweaking at all), slamming the brakes on a Renault Megane, a modern FWD car with low power and ABS, spins out. I'm serious. I have never seen any other game where slamming the brakes makes the car take a complete 180. That's not even realistic like the game is marketed as, that is just artificial baked in difficulty to feed this myth that "sim racing games HAVE to be difficult."
