The publisher put out 88 games (including individual iterations of multiplatform titles) across six systems, selling roughly 20.9 million software units in the 12-month period. Its efforts were focused primarily on handheld releases, with 30 games on DS -- plus three more for the 3DS launch -- and 29 for PSP. The company's two bestselling titles during the fiscal year, however, were for home consoles: 2009's still-kicking Tekken 6 accounted for 1.15 million unit sales on PS3 and Xbox 360 in the US alone, and Naruto: Ultimate Ninja Storm 2 sold 1.1M units worldwide on those same consoles, according to the company's financial highlights document [PDF].
While Naruto performed above initial expectations, Enslaved failed to muster numbers in line with even the revised sales forecast reset by Namco Bandai in November. Ninja Theory's action-adventure had to settle for 730,000 units sold across PS3 and 360, falling short of the hoped-for 800K mark. As for Splatterhouse and Majin, the publisher did not report their individual sales, as both titles' performances seemingly fell below 400K units (Namco Bandai's cutoff line for "Main Game Titles," as they appear in the financial highlights report).
For the current fiscal year, which began April 1, Namco Bandai forecasts continued gains resulting in ¥8 billion in profit. The publisher has plans to release 90 games during the period, including 26 titles bound for PS3. Props to anyone that can name three of them! (No googling.)
