Slorkuz posts that yesterday, February 11th, marked the four-year anniversary of World of Warcraft's release in the EU, and Blizzard is throwing a few contests to celebrate. You can see all of the giveaways over on their site -- there's some nice Swagdog and Dell gear to win for coming up with a great t-shirt slogan, a piece of fan art, or answering some lore questions. Unfortunately, participation in the contests is limited to only a few countries, due to local rules, but if you're interested and able, have at it.
Congrats to Blizzard and the EU for four full years in Azeroth! North America had our anniversary late last year, and WoW Insider put together a look back at what it was like for us. We all (including the EU) got the anniversary pet as well, so apparently, other than these contests, Blizzard is just giving this date a nod rather than a big in-game celebration. But there's always the ten year anniversary -- we'll see you in 2014!
