More real world driving roads, like they did with the Tokyo Expressway. Hakone skyline would be perfect, as well as any of Japan's other famous touges. Imagine having them as free-roam lobbies that players can drop in and out of, hang out in the parking areas, drive with friends, etc. My favorite parts of the first GT games were the mundane details that added realism, like searching for a used car at used car dealership, changing the oil, getting a car wash, etc. I'd love to see that nuanced attention to detail return. I know I'm in the minority, but I love how much Polyphony used to geek out when it came to the cars. I loved the fact they had a bunch of different versions of the same car, and choosing an FTO GP version R over a GR or GPX always made me feel more connected to the car, and that it was my own. Being able to geek out over learning what difference trim levels made was always fun to me. I love GT scapes, it would be really cool if they became functional, such as taking your R33 in for an oil change and watching it pull into a service bay at Nismo Omori factory for example, or choosing one as your home garage that would automatically display your current car in that setting for the main screen. To me, I always felt that the Gran Turismo series was best when it just let itself be a game to turn people into automotive otaku. The insane attention to detail, the little nuances like the used car dealers with the rotating selection of cars, and the 5 versions of one model of Daihatsu Kei car. Keep the GTsport series going for those who like to race, give Gran Turismo back to those of us who love cars and just want a huge detailed single player career so we can drive some of the world's best tracks and roads while staring at the inside of a Daihatsu Move Aerodown Custom through a VR headset.
