Due to lack of information about the game on the box of Diablo 3 and the lack of access to the game because of technical problems, the Consumer Federation warned the game manufacturer Blizzard.
Blizzard has failed to inform players about permanent Internet connection requirement on the game box. Also in connection with the registration requirement on Battle.net, Blizzard’s internal network, there is no information about entering the game key as well.
The game can only be used if the player is logged into his/her personal account on Battle.net.
Now, Blizzard has time until 13.07.2012 to cease and desist because of antitrust violations (whatever that means, we are not quite sure yet).
