Amidst restructuring, Sega announced its acquisition of Marvel Puzzle Quest developer Demiurge Studios. The Sonic the Hedgehog creator has also invested in UK studio Space Ape and established a majority stake in US studio startup Ignited Artists.

The moves comes after Sega cut 300 jobs last month to shift focus from console to digital and mobile.

“We’re constantly evaluating the independent mobile game space for studios that fit our vision of fun, high-quality gameplay experiences,” Sega Networks CEO Haruki Satomi said. “Demiurge underscores our commitment to investing in the West and complements our current roster of US and European mobile studios, including Three Rings and Hardlight. In addition, our strategic investments in Ignited Artists and Space Ape Games solidifies our commitment to publishing quality games across the globe.”

Demiurge may be best known for mobile title Marvel Puzzle Quest, but it has also been involved in the development of many triple-A console releases including Rock Band, Borderlands, Mass Effect and BioShock.

Writing on its own website, Demiurge explained that its acquisition by Sega won’t lead to major changes for the studio. Its CEO Albert Reed will join Sega as VP of product management, although he will continue as Demiurge’s studio head.

“Through some miraculous happenstance of fate, we’ve founded a partner that likes us just the way we are–warts and all,” the developer wrote. The studio will continue its work on Marvel Puzzle Quest, stay in its office, and won’t change names as a result of the buyout.

“Demiurge and SEGA share a vision for the future of mobile gaming: putting gamers first,” said Reed. “In today’s mobile games you must listen to your players and find new ways to keep them engaged. Our success with Marvel Puzzle Quest comes from our focus on iterative design and testing, with our players in mind. Joining SEGA Networks lets us align with a truly global partner that shares our approach to design, so together we can create the kinds of entertaining, fun and engaging games we all want to make.”

Demiurge also explained that the company’s long-term goal was to “build a publishing organization.” Becoming a part of Sega–and tapping into its knowledge base of free-to-play games domestically and abroad–allows the studio to do that.

Space Ape CEO and founder John Earner expressed similar hopes for expanding to new markets with the Sega partnership on their side.

“We are delighted to partner with a company with the gaming pedigree of SEGA,” Earner said. “Our last release, Samurai Siege, was a success in the Japanese mobile market. Japan is now our second-largest market and contributes around a third of our revenues. With Sega Network’s experience and record of success, we are confident that Rival Kingdoms, our next game, and future titles will be able to improve upon this success.”
