According to a Eurogamer report, Blizzard has told journalists that it will not allow reviews of Starcraft II: Wings of Liberty to be published before the game's launch next Tuesday (July 27).
Eurogamer said that, from its conversations with people at Blizzard, that much of it has to do with Battle.net.
Blizzard has told Eurogamer that the new Battle.net and the online features that will be introduced with it are "so integral to the game that it would be both impractical and undesirable for press to review it before servers go live." While a good portion of multiplayer in Starcraft II has been revealed thanks to the public beta test for the game, Blizzard has done a good job of keeping the game's campaign mode secret, as well as the game's "challenge mode," which allegedly bridges the gap between single and multiplayer.
For a more colorful take on this story, we offer this from Rock, Paper, Shotgun:
In what journalists are calling a “Dick Move”, Blizzard has announced that there will be no reviews of StarCraft 2 before lunch. Would-be reviewers are going to have to wait until after everybody in the office has had lunch before posting their review of the hotly anticipated RTS.
Wait, hang on. Sorry, I misread my RSS feed. Blizzard has announced there will be no StarCraft 2 reviews before launch. Before the game’s launch, on Tuesday, when the BattleNet servers go live. According to Eurogamer Blizzard was “unable to offer an official comment at the time of writing”, though they gather that it’s to do with Blizzard not wanting anybody to play the game without the full suite of BattleNet features.
