While the attach rates of the 3 consoles are similar, best-selling Wii titles skew heavily toward those developed by Nintendo. A new metric must be introduced that is more relevant to 3rd party developers, as they decide on which platform to develop games.
3rd Party Attach Rate (3PAR) is a metric calculated by filtering out 1st party titles from each console's attach rate; it represents the average number of 3rd party titles purchased by a given console's owner.
For example, Nintendo has sold 439.83 million software units. Of those, it has published 232.19 million, leaving 207.64 3rd party published titles. With a userbase of 65.16 million, its 3PAR is 3.19. The 3PARs for all three consoles are:
Wii: 3.19
PS3: 5.18
360: 7.42
HD (PS360): 6.39
With a similar amount of consoles, PS360 has double the 3PAR of the Wii.
Potential explanations for this large discrepancy include:
1. Higher quality PS360 titles: 3rd Party titles on the HD consoles are of much higher quality than those released on the Wii.
2. Wii owners heavily prefer Nintendo titles: Many Wii owners may only trust Nintendo to make good games and thus shy away from games not from Nintendo.
3. Nintendo games are unmatched in quality: Nintendo's titles really are that much better than those created by 3rd parties and thus sell well based upon quality, and not brand trust.
The argument that Wii owners are casual may also hold, but since the base attach rates are similar across all 3 consoles, it fits under explanation 2: casual gamers trust only Nintendo's casual games.
While explanation 1 suggests that third-party developers could theoretically create games that sell well, it is difficult to discount explanations 2 and 3 in explaining the 3PAR discrepancy. And it is difficult to justify explanation 1 when many critically acclaimed 3rd party titles have not sold well on the Wii.
With 3rd party developers announcing their shift toward PS360, it is difficult to argue against them when the Wii's 3rd party attach rate pales so much in comparison to PS360.
