Sega has announced a $200 million write-off after acquiring Rovio, the studio behind Angry Birds. The $776 million purchase hasn't panned out as expected, as Rovio struggles amid fierce competition in the mobile market, dropping its valuation to about $578 million. On a brighter note, Sega's Sonic franchise is doing well, with Sonic Racing: CrossWorlds receiving positive feedback for its gameplay and customization. Is Sega's focus on Sonic the right strategy moving forward?
