Big acquisitions and mergers in the video game industry are fairly commonplace, with big publishers like Activision and Electronic Arts making moves frequently. EA CEO John Riccitiello, however, doesn't believe there will be as much activity moving forward, according to comments he made to the Reuters Media Summit. EA made the biggest splash most recently when the company purchased leading independent developers BioWare and Pandemic in a deal worth up to $855 million.

"Is (the industry) ripe (for mergers), or has it already been picked? I would argue that it's been largely picked," Riccitiello said. "That doesn't mean it's done. I think there will be more consolidation to come. But let's just say a lot has already happened."

He said that game companies just need to focus on making quality games with strong creative teams. He also noted, "There's a lot of growth in what is the nontraditional arena, so that would be micro-transactions, subscription revenue, ad revenue, new types of models, casual games."
