Good numbers for the 360 and ps3 whith both seeing increases.

Good to see that the Wii/PS3 are edging higher. Very surprised that PS3 owners don't own more games.

^clutching straws anyone?

look at the install base of 360 v ps3 in NA its not a fair attach rate comparison

a fair comparison would be the EU attach rates as both ps3 and 360 are similar install base.

@rolstoppable - Since these are lifetime tie ratios, usually the console that has been on the market has an advantage. The 360's 12 - 18 month headstart is reflected in these numbers.

Reading the full analysis from gamasutra, it will be interesting to see sales for the month of october, cause their analyst suppect that the 360 is getting it's new sales from the PS2 crowd.

...So far this year the Wii has sold the most software for 2008 which in turn we see an increase in it's attach ratio. If Wii hardware sales crazy like analyst thinks we will see that attach rate go down like a 5 dollar whore*.

*traditionally it's been a 2 dollar whore, but with the current economy we're see an increase.

Attach rates mean absolutely nothing nowadays.  Why?  They don't include downloaded games.  Literally, I own over 30 games for my PS3 altogether if you include both disc-based and DLC, which IMO, should most certainly be included in those numbers.

I understand why it's not, because it'd be very hard to track, but it should be.  Regardless, I have more than the average for all 3 systems, even if you only include disc-based games.

attach rates will be better for consoles that have been on the market longer, for systems that sell slower and for consoles that are often when they are not balanced in demographics very well.

well actually i compared both combined lifetime and install base, but EU is a better look for attach ratio as they have similar install bases.
