VAMP, my response to you would be to stop thinking in terms of attach rate. How a game sells is what matters, not how it sells relative to the size of the install base. This notion that you can simply multiply the software sales of a smaller console by a scaling factor is inherently flawed. If that were true, then Halo 2 would have been the best-selling game of the last generation. Look: the XBox had 1/5 the install base of the PS2, so multiply Halo 2's 8m sales by 5 = 40m sales! ZOMG!
Obviously that's a flawed comparison. Third parties sold vastly more software units on the PS2 than on any other platform, because the total number of consumers available to purchase their games was so much larger. I don't think they cared very much that they could have had a better attach rate on the other systems. And remember, the Gamecube had the highest attach rate of all time. It also had one of the lowest third-party support levels of any console. Those two factors are directly linked.
Think in terms of sales, not attach rates. :)
Now for my second topic. Ahh, Legend. I see you continue to miss the point as well. Posting a list of how well Nintendo sells relative to other publishers, then using this to imply that third parties shouldn't develop games for Nintendo systems. First of all, this is a logical non sequitor. The gaming market is not a zero-sum one; just because Nintendo first party games sell well does NOT mean that third party games must sell poorly. It's entirely possible for both to do strong sales; see for example the NES, SNES, Gameboy, and DS. Or to be more blunt, just because Nintendo first party software sells well on the DS, does that mean every third party should support the PSP? That seems like a losing strategy. Software sells great on the Wii; there's more than enough room for strong sales of both first and third party stuff.
Secondly, have you ever considered that the reason Nintendo sales are so strong in Japan is precisely BECAUSE third parties have been ignoring the Wii? The 360 + PS3 install base in Japan is about 1/3 the size of the Wii. If Namco, Square, and Konami are getting killed in Japanese software sales, the correct response is not to complain "Wii first party games are too strong - let's develop for competitors with poorly selling platforms!" Obviously the answer that makes the most sense is to develop for the profitable, dominant Wii and DS platforms. Once third parties start supporting the market leading console, Nintendo will stop having such a skewed "Pacman" on the software charts.
Again, this is not a zero-sum market. It's entirely possible for first and third parties to succeed on the same platform. Just because millions of people are buying Mario Galaxy doesn't mean that millions also aren't buying Resident Evil, Mario and Sonic, Guitar Hero, and so on. As I said in my previous post, the Wii just moves software PERIOD.
