Capcom's new DRM requires you to be logged in on PSN to launch the game.
A couple of disgruntled PlayStation 3 owners that purchased Final Fight: Double Impact found out that the game won't launch if you are not connected to PSN with the account that has purchased the game. If someone tries to launch the game while not connected to PSN, they will be greeted with the following message, "Sign into PlayStation Network. (80029516)".
