Buying Games in Bulk?

[milano]

I think that the reason many people (including Kwaad above) say that the Wii has a poor attach ratio is that their definition of an attach ratio is:

No. of software units sold in a given period : No. of hardware units sold in a given period

which seems to me to be incorrect, because the software is being purchased by the whole installed userbase, not just by people buying hardware units. This would then give a low ratio for the Wii, not because the software sales are low (they aren't), but because the hardware sales are so high. To illustrate why this ratio is misleading, consider what would happen if software sales stayed the same, but hardware sales fell by 50%. The attach ratio would then double, but are people actually buying more software? No, they're not.

I can understand why some people might consider that ratio valid, because in the past someone buying a game console might buy around 5 games to go along with it. That doesn't seem to be happening with the Wii, but it does seem that Wii owners are buying games, they're just not buying them all in one go. As far as I can see from the VGChartz figures, in any given week, the Wii software sales are pretty close to the X360 sales, even though the Wii's installed user base is only about half of the X360's. Even if you take out Wii Sports (which I don't think you should) and Wii Play (arguable) the Wii's software sales are still higher relative to the userbase (by which I mean total hardware sold).
