The No-LAN Controversy - A Closer Look
by Schizotypy
July 27, 2009
Last month's news of StarCraft 2's retail release without LAN mode has brought quite a bit of controversy and mixed reactions - mostly negative (86,000+) - among the Blizzard community. I will take a closer look why LAN will not be included with release, some of BNet 2.0's new features, and piracy. The original StarCraft's popularity, especially in the Asian market, was made possible mostly via LAN in small leagues/tournaments/cafes/LAN parties. Blizzard say the features Battle.net 2.0 will counter-balance the lack of LAN but the details of these features are yet to be released. The question is, will it be enough?
Why no LAN?
Blizzard's plan to not implement local area network (LAN) with StarCraft 2's release was announced last week into the eyes and ears of unwelcoming fans. Why use Battle.net as the only form of multiplayer game mode? Well, a day later after this news, Blizzard responded with two reasons to both disappointed and confused fans why LAN will not be included:
* To help curb piracy.
* Force players to fully utilize the new Battle.net.
Since a player does not need a valid CD-key to play single-player or LAN, the game can be easily downloaded and "cracked" to start up LAN/multi-player games. Also, according to Karune, Blizzard wants more people on the Battle.net servers so more resources can be devoted into the new online platform. They want everyone, casuals and e-Sports professionals alike, to play on a single network.
From Blizzard's PR, Bob Colayco:
Blizzard Quote: (Source)
"We don't currently plan to support LAN play with StarCraft II, as we are building Battle.net to be the ideal destination for multiplayer gaming with StarCraft II and future Blizzard Entertainment games. While this was a difficult decision for us, we felt that moving away from LAN play and directing players to our upgraded Battle.net service was the best option to ensure a quality multi-player experience with StarCraft II and safeguard against piracy.
Several Battle.net features like advanced communication options, achievements, stat-tracking, and more, require players to be connected to the service, so we're encouraging everyone to use Battle.net as much as possible to get the most out of StarCraft II. We're looking forward to sharing more details about Battle.net and online functionality for StarCraft II in the near future."
There is one rumour amidst (not yet confirmed or finalized) is that LAN will be playable via authentication with BNet 2.0. But this defeats the purpose of LAN where people are in areas with no internet (yes, these places DO exist and some are in the United States and other developed countries). But Blizzard's counter-argument is that internet is now widely available.
