They weren't doing too badly but it is worth noting that their revenue grew by 89.8% in 2007 (http://www.i4u.com/article17075.html).

This is in part due to the unexpected roaring success of the Wii. Such a feat will be difficult to pull off in the future (although Nintendo is remarkably left-field thinking and might surprise us).

So before the Wii and DS, I bet that the profit-per-employee was probably less than that of a Goldman employee.

I would be really interested in a 10 or 20 year profit-per-employee comparison between Goldman and Nintendo.
