Or just patch the game to fool it into thinking it's connected, and allowing offline play.
I'm sure my off-the-cuff suggestion is in no way difficult to implement! It's probably just a switch somewhere. Check under the stack of papers over there...
People continue playing the game and doesn't buy every future releases and dlcs. Massive imaginary losses and company doesn't grow as fast (boo very scary). Lot of assholes do this sort of shit like Nintendo going after emulation and old games.
