If only the online aspect of the game is your interest, well yes.
Then we can say that it's unplayable.
But there are the special events that are great and not at all easy, making you play with the setup to try achieve gold medals.
On the support forums and even here there's people organising time trial events weekly.
And you can have some quite good race weekends against the AI.
The game is perfect? No it isn't, i don't think nobody of the console version users will deny that.
But in driving physics and wheel FFB it's the best game on console for now.
Let's wait and see what the incoming update brings,for what we know with personalised offline championship mode and the personalised online lobbies i would be a good step forward.
Me self uses project C.A.R.S meanwhile for my racing leagues, from today off i will be trying out the closed beta from GT sport also.
But for sure i also keep playing assetto for the physics, feeling and fu..ing hard special events
Only thing that really matters in this hobby is having fun with what you're playing.
Hopefully the next update make you enjoy assetto on the way you want to enjoy it
