A minor furor has erupted online in the last few days over some gamers being unable to play StarCraft II in offline mode even after authenticating their game with Blizzard's Battle.net service. Blizzard has always said that players should be able to get a 30-day "grace period" in which the game will run without connecting to Battle.net after a successful authentication, at which time it requires re-authentication. Some gamers have been locked out after every reboot, causing considerable consternation.
