Capcom Combats Game Sharing With Always On PSN DRM

In an effort to combat what Capcom calls "rampant" game sharing, it has implemented a form of DRM in Final Fight Double Impact that prevents users from booting up the game unless they are logged-in to their PSN account with an active internet connection.

This restriction emerges on top of a 24-hour rule that prevents shared titles from being accessed by more than one account in the span of a day.
