Running through the NPD results for 2009 (U.S. only in retail dollars), it looks like Nintendo first party Wii titles sold 27.5 million units for a total of $1.53 billion at retail. In contrast, overall Wii software sales were 72.4 million units and $3.23 billion.
I think that this illustrates an obvious point: Nintendo first party titles dominate on the Wii.
Nintendo captured 38% of unit sales and 47% of dollar sales, leaving the rest for third parties. The average Nintendo first party Wii title sold for $55.63, while the average third party title sold for $37.85. Nintendo first party titles captured the top 6 positions, 9 of the top 10, and 15 of the top 21. – Wedbush Securities analyst Michael Pachter
