Peter Dille of SCEA has claimed the PlayStation 3 enjoys a higher attachment rate than the Xbox 360, who by the way, should be selling "twice" as much stuff.
Senior exec Dille goes on to use some blockbuster figures that show his claim holds true, and even drags Metacritic into this whirlwind of corporate product chest beating.
"If you factor in Xbox 360’s longer time in the marketplace and larger install base, Xbox 360 should be selling twice as many software units as PS3 if attach rates were equal - and that is just not what we are seeing at retail with many multiplatform titles," Dille tells Gamasutra.
Sony enjoys a higher attachment rate in the US on Grand Theft Auto IV, Prince of Persia, Tomb Raider: Underworld and Street Fighter IV.
GTA IV enjoys a rate of 26.9 percent on PS3 compared with 23 percent on Xbox 360, which is thanks to its "rich legacy with the PlayStation brand" explains Dille. The game has sold 3,362,196 units in the US on Xbox 360, with only 1,959,798 units on PS3.
Moving on to Metacritic, Sony cite from this month's figures that they enjoy a higher percentage of their platform games with scores above 80. "This means one out of every three PS3 games have an 80+ score, while Xbox 360 has one out of five titles that have garnered 80 + scores," said Sony.
Rubbing salt in the wound, they also suggest that maybe Microsoft's prime days are already behind it. "Of the top 10 scoring PS3 games on Metacritic, 7 were released in 2008 or 2009."
"On the other hand, most of Xbox 360’s top rated software titles were released back in 2006 and 2007, when the console had little to no competition, with Xbox 360 only releasing 4 of its top 10 rated in 2008 or 2009," Sony continued.
