Wrath of the Lich King is the fastest selling game of all time beating the old champion: Burning Crusade. Believe it or not, Blizzard is saying 2.8-million people picked up the expansion to World of Warcraft and are currently sitting at home forgetting to eat their dinner in the first 24-hours of launch.
This probably doesn’t come as any surprise to Burning Crusade owners, but think on this… you can’t play Wrath of the Lich King without the core game and the Burning Crusade expansion. New adopters of the WoW haze will be investing a good deal of money, before monthly charges, to get into the full experience of Lich King.
The original Burning Crusade expansion sold 2.4-million copies in the first 24-hours, in some ways this is disappointing because their was only a minor influx in this new expansion. It’s hard to complain about epic sales on a game expansion, what other title can boast number so high for an expansion pack?
The real question is, how many gamers have taken days off of work to get their Death Knights to level 80 first?

Microsoft has proven the achievement system is one of the best ways to add replay value to a title and inspire players to overachieve in every game title, no matter how obscure. Now, Blizzard joins the battle for achievements by bringing them to the Blizzard franchises.
As the Wrath of the Lich King beta lives on, the world (and software behind it) is ever changing. Apparently, the rune system has changed a lot since its first inception. This requires a delicate balance, as the goal is a well rounded Death Knight class without epically overpowered features. Too much power and people will feel cheated while others feel overly destructive. End result, everyone would be a Death Knight.
It’ll be more interesting to see what NEXT months NPD’s are.
