Nintendo also has an incredible track record of not being able to foster healthy relations with third party developers, and being outright hostile to indie developers (see: http://www.crunchgear.com/2011/03/21/fils-aime-nintendo-not-interested-in-garage-developers/ http://www.crunchgear.com/2011/03/21/fils-aime-nintendo-not-...). The Wii, outside from the first party titles, was pretty much a wasteland at least compared to the offerings of Microsoft and Sony. This I think has led to the Wii having a fairly low attach rate and, at least anecdotally, the number of consoles that were bought for Wii Sports and have been gathering dust ever since.
