- Alot more real and fantasy race tracks, up-to-date with todays quality and graphics. Circuit de la Sarthe, Spa-Francorchamps (old and new), Monza (with oval), Ascari, Silverstone, Raceway Laguna Seca, Zandvoort, Imola, Yas Marina, Monaco GP, and more real life tracks. Oh, and all of the original Gran Turismo tracks!
- More real life, every day cars. Older and newer. Supra's, RX-7's, Charger's, GT40's and the hundreds of other loved cars. And just about every car from every Gran Turismo. Ever. Plus more cars. Just because dreams.
- More Group C/Le Mans Prototypes and vintage race cars like in older Gran Turismo's etc! Sauber C9, 787B, R92CP, Minolta etc etc.
- More in-depth tuning and upgrade/downgrades of power and weight of all cars. I would like a Supra with 1500 HP. Just because you can.
- A way deeper and bigger offline "GT Mode". More championships, leagues and endurance races. I like them.
- Bring back the various coffee break challenges, missions, driving licenses (that were actually hard) and more from older GT's.
That's on top of my head at the moment. Probably a ton more, given more time.
