Activision’s Modern Warfare 2 has become the biggest launch title in entertainment history; something that comes as no surprise, seeing that Activision is the worlds biggest video game publisher because of the Call of Duty franchise.

In its first day, the game sold an estimated 4.7 million copies in North America and in the UK, reports internal Activision estimates, with estimated sell-through sales of $310 million in North America and the UK alone in the first 24 hours. Meaning that, this could mean that Modern Warfare 2 did sell the recent estimated 7 million copies worldwide on day one - this report only covers the UK and North America sales, not the entire planet’s day one sale of the game.

“The Call of Dutyfranchise has become a cultural phenomenon showing the power of video games as an entertainment medium,” said Mike Griffith, CEO, Activision. “The shattering of these entertainment records is a testament to the compelling, cinematic and uniquely engaging experience that the Call of Duty brand delivers. Modern Warfare 2 has taken interactive experience to unprecedented heights setting a new standard for entertainment.”

But, the question still remains. How much did Modern Warfare 2 sell worldwide on day one?

Recently revealed that its 360’s development began in April, its developer, Square Enix, have stated that the 360 version of Final Fantasy XIII has “no chance” of compromising with the PlayStation 3 version of the title.

When speaking to VideoGamer, XIII producer Yoshinori Kitase had this to say about the compromises between the two versions of Final Fantasy XIII.

“The team is targeting to create an equal experience on both the 360 and the PS3, so there are no limitations. For example, right now we’re working on the PS3 version first, and once we’ve completed that we’ll really know how much game there will be to fit onto the Xbox 360 discs,” said Kitase.

“So we don’t know how many discs it’ll be housed on for 360, but there won’t be a chance that we’ll compromise anything because, oh it didn’t fit in the 360 discs so we’ll have to take it out of the PS3 version, or vice versa.”
