"The May 2011 NPD data was just released for video game hardware/software sales, and L.A. Noire was in the #1 software spot for the month, but the NPD data did not show the sales breakdown between the PS3 and Xbox 360 versions of the game.", says CoffeeWithGames in the introduction section.
CWG continues, "The chart below is not designed to be a replacement of NPD data, but to be a supplement with the NPD data for developers and investors alike, that may be interested in sales data.
Were more crimes apparently solved on the PS3 or the Xbox 360 in the first 14 days after L.A. Noire released, based on the game's sales ranks in May? Let's take a look!"
