Question: the iOS game, Street Kart Racing (noted for its involvement of Rosberg), not only uses real-time day/night cycles for its courses, but also accounts for the time zones of each course. What do you think of this being implemented into Gran Turismo? (Likely in a future title, or one of its subsequent updates.) I think it'd be an easy way for each course to offer a bit more verisimilitude, and even the stars could reflect this. I think GT6 had a little thing about doing this, but I wonder if this applied to each hemisphere, as well? AFAIK stars are much like the seasons, in that they're "inverted" between the hemispheres; a constellation you can't see on a clear night sky in England or Seoul is likely visible within clear night skies seen from, say, Argentina or New Zealand. It doesn't even require all courses (namely the GT-original courses set in fictional locales) to have a precise location - the Special Stage Route X course could operate off of Pacific Standard Time, as one example.
And the events could reflect this, too. Like for the most part in GT League, most circuits would be driven during the daytime. For online races, there could be a race set in each major region, so that not all courses will be at night or all at day. For example, if you're American and you're only are able to play the game late at night, you'd be able to race at Suzuka or Fuji when the sun is still rising on the circuit. But this could especially apply to online endurance races, where ideally, there would be these much longer races as part of an official tournament. Imagine a Bathurst 12h, Suzuka 1000km, Nurburgring 24h, or Daytona 24h, but in Gran Turismo. (Granted, for all endurance races in the campaign, and virtually all endurance races online, I'd make them about as long as they were in Gran Turismo 3, with three hours as a hard maximum, and most online endurance races being about an hour long on average.)
