This is probably my most anticipated game of the gen.
All the Gran Turismo OGs who loved GT Sport know how good this game could be. The series' older classic modes integrated with Sport's competitive online has the potential to be one of the greatest console racing games ever made (I'm not exaggerating).
Assuming they've already fine tuned/revamped some of Sport's annoyances like it's mediocre FFB, FOV in cockpit view, etc, then all they really need to do is bring the content (modes/cars/tracks). Sport launched with less than 200 cars (the price Kaz paid for his attention to detail), compared to Forza's 700~, which was its biggest critique. They've begun to outsource the car models so they might be able to double, or hopefully, triple Sport's launch cars. I also hope they drop Thrustmaster for Fanatec as their official racing wheel. Either way, I can't wait.
