Stumbled upon an interesting article at 1UP.com, it's about TOSE, a Kyoto-based company with more than 1,000 employees. They mostly port games to other platforms, but also develop entire games for big companies such as Capcom and Konami. The interesting part is that almost no one knows about this company, they are never mentioned in the games they create, they let the developers they work for take the credit and try very hard to remain secret. Their list of clients include EA, Sega, Nintendo, Sony, Square Enix, Take-Two, THQ, Namco and of course Konami and Capcom.
