Early data is in and it looks like StarCraft II: Wings of Liberty has become the fastest-selling game of 2010 to date and one of the fastest-selling PC games of all time. VGChartz estimates that around 1.8 million units of the game were sold on day 1 across the Americas and Europe including both physical retail sales and Battle.net download sales. This figure does not include players in Korea where it is virtually impossible to accurately estimate how many people will have purchased the game due to the way in which it is sold - mainly via time cards and also with Blizzard announcing that World of Warcraft users with an active account in Korea would be able to play the game free of charge. The number of players in Korea playing the game on day 1 could be as high at 3-4 million but only Blizzard will know for sure.
Breaking down the 1.8 million sales in the Americas and Europe, VGChartz estimates that around 31% or 570,000 units were sold digitally via Battle.net (obtained via a study of order numbers during the first day of sale) with the remainder coming from physical retail sales and 57% of total sales coming from the Americas with the remainder from Europe.
We expect Blizzard to make an official announcement in the coming days and hopefully they will shed some light on the success of the title in Asian markets as well. The current record-holder for day 1 PC sales is the World of Warcraft expansion Wrath of the Lich King, which sold 2.8 million units on day one, including sales in Asia. It will be interesting to see how Blizzard quantifies total sales and whether StarCraft II will be revealed as the new fastest-seller.
