Once you've bought the disc, you still have to download, intall and updtate the game, which takes hours. Then if you want to play the single player campaign, you have to download that separately, which again takes ages. THEN if a new update is released, even if it had nothing to do with the single player campaign, you can't play offline until you've updated it. These updates are large and take an hour or so to download.
What they've done is taken a game that could've had potential, and made it almost completely inaccessible.
It's an absolute joke.
