WoW addicts have a new reason to celebrate. And no, it’s not because they found a new in-game girlfriend. Blizzard Entertainment released their second expansion pack for World of Warcraft, Wrath of the Lich King ($39.99 – $69.99) available in standard and collector’s edition. This expansion pack features a new high-level player continent called Northrend in the land of Azeroth. Blizzard also expanded the game’s Player vs. Player (PVP) options and added new dungeons, raids and improved the game’s graphics. A new Hero class is also thrown in the mix along with new monsters, creatures, a profession called Inscription and more.
