I mean more (offline) championships, missions, cafes, circuits, etc.Well as you said, it is short, so I'm not sure how much time you can pass with it.
We're getting new content very soon though, although it might not be what you are referring to by "content"
There's actually quite a lot of events, with a similar setup to GT5/6.
I understand GT Sport was delisted but if I got the disk version would it enable me to be able to play GT offline with no internet at all. I'm considering if this might be an option for when I travel in an RV and am out of internet capability as a way to pass the time if I bring a PS5 along....
