The consumer games division made ¥6.3 billion ($68.2 million) in operating income, returning to profitability despite a year-over-year drop of 7.5%. The profits in this division were driven by ridiculously strong sales of Mario & Sonic at the Olympic Winter Games (6.53 million copies!), as well as million-plus sellers Aliens vs. Predator (1.69 million), Bayonetta (1.35 million), and Sonic & Sega All-Stars Racing (1.07 million).
