Attach rate will define Grand Theft Auto IV’s success, not raw sales figures

UBS analyst Ben Schachter has some tips for those of you planning on benchmarking Grand Theft Auto IV’s sales against previous iterations - namely, don’t.
Back when Vice City and San Andreas were flying off shelves, the PS2 and Xbox were the dominant platforms - and there’s nowhere near as many PS3s and Xbox 360s out there. Schachter rightfully proposes that GTA IV’s attach rate (number of units sold divided by the number of Xbox 360/PS3 consoles in homes) is the more accurate metric for success.
“Should Metacritic scores come in above 95, attach rates could rise to 30%+, implying potential U.S. sales of 7-8mm units (scores for the past three GTA titles were 95, 95, and 97). Any attach rate above 26% would beat expectations in our view,” he added.
