Sales research firm Chart-Track has provided Gamasutra with UK launch week performance figures for Rockstar's Grand Theft Auto IV, showing the title setting combined all-time records for first-day and first-week sales of 631,000 and 926,000 respectively. GTA4 was on sale for five days in its first week.
Despite the milestone, Chart-Track notes that neither the Xbox 360 or PlayStation 3 version unseated its predecessor, Grand Theft Auto: San Andreas, on individual levels. The PlayStation 2 version of the game managed to rack up 501,000 units in its first day and 677,000 in its first week, which consisted of only two days.
GTA IV's unit sales put first-day and first-week revenue at GBP 27.3 million (US$53.4 million) and GBP 39.9 million (US$78.1 million) respectively, figures that attribute higher revenue to GTA IV alone than to any other total week so far in 2008, with the exception of the first week in January.
Sales of the Xbox 360 version of the game edged out those of the PS3 version, 55 percent to 45 percent. Both versions set UK platform sales records, with GTA IV topping Halo 3 on Xbox 360 and Gran Turismo 5 Prologue on PS3. Both consoles saw unit sales more than double from the week prior to the game's release.
