TBH, I'd love to see the Tokyo Expressway courses, the Special Stage/Clubman Stage courses (especially SSR7, which could connect some of these areas) and the Tokyo R246 all be somehow consolidated into a broader, singular location with many variants. Call it "PD's view of Tokyo," so to speak. I wouldn't mind if all three locations and their layouts didn't necessarily have the same name or even precisely same layout (as it could also be a chance to improve on the designs for the other, older courses) but they could still bring back the basic layouts for these courses, and they could all be inter-connected. Heck, there could even be this unranked online mode where you can just cruise on this open map like a lobby of sorts, and challenge other racers. (Also to note: didn't some of the PS3-era Special Stage courses have unfinished roads you could drive on via hacking? As if it may've been planned to use the exit ramps?)
