Attach Rates

The attach rate of a console is a measure of how many console specific games are bought per console. For example, if the average PS3 user buys 6 games, then the attach rate is 6:1. Attach rates can also apply to particular games, too. For example, if 1,000 Xbox 360s are sold and 500 copies of GTA IV have been sold for the Xbox 360, then the attach rate could be seen as 500 / 1,000 = 50%. The attach rate can offer a supplementary view of sales performance, in addition to those absolute sales numbers.
