Anyway, I think I have decided what I am going to do. I'm not much of a planner, but I think I am going to do something like:
a) Get GT4.
b) Get all the gold licenses.
c) Buy a Mazda miata or something and start winning races.
d) Complete the beginner hall.
e) Complete the professional hall.
f) Win the Nurb 24 hours (in B-spec mode) to get an F1 car.
g) Win the F1 championship in the F1 car, winning every race by as big a margin as I can manage (I know you can win this in a non-F1 car, but it's an F1 championship so I want to drive an F1 car).
h) Drive the Sauber C9 off into the sunset.
Edit: When it says 'complete' the professional hall, etc, does that mean you have to win every race and every championship in that hall? Or just every championship?
