There are some caveats to the information, most of which revolve around how much outsourcing the Big N does. Nintendo makes so much money for having so few employees (3000 full-time), because many of the company's necessities (external development, manufacturing, public relations, etc.) are handled by outside companies. Also, don't think this means that Nintendo is compensating its full-time employees too generously. Goldman's average (by mean) employee received $660,000 in 2007, while the average salary at Nintendo was $90,900.
