Very poor. No need to turn my PS5 on for another month.
Even though I would like them to sort this game out for the many problems, many of which would be easy to fix, or at least improve, I hope that this poor delivery of additional content over the last few moths is a sign of them working on the next game. Because if they are not, it is a kick in the teeth for loyal users.
And even if there is another track plus these three cars, a couple of menu items and scapes, it would still be disappointing if that is just it. imho of course.
