Sega of America confirmed today that it has laid off a number of its employees. The company, a division of the large Japanese video game publisher, did not say exactly how many jobs were lost.

A spokeswoman for Sega confirmed the layoffs. She said, “As the gaming industry continues to evolve, companies must adapt and adjust in order to compete and succeed in an ever-changing environment. As a result of this, Sega of America has recently undergone a restructure that will enable the company to focus efficiently on developing new and existing content across digital platforms as well as continuing to focus on key brands for packaged goods.”

Sega is the maker of Sonic the Hedgehog, a longtime franchise in the game business. But the company has had trouble coming up with new hits, and it has gone through several restarts in its U.S. operations. More recently, it has been acquiring makers of real-time strategy games such as the recently shipped Total War: Rome II game and role-playing games such as Atlus.

We’re trying to find out the exact number, but we’re told the number is small.
