There's been a slow and steady decline in online since the game launched and it's never reached the heights of GT5, as you would expect with far fewer sales. Most lobbys are either drag, drift, cruise, free run, or racing on RS tires, none of which hold any interest for me. I've tried many times to run my own lobbies, usually 450-500PP on SH or SM tires and you get very few lookers and few that actually stay.
