Fighting game Tekken 6 sold 1.15 million units in the US alone during publisher Namco Bandai's 2011 financial year - despite the game launching in 2009.
Ninja Theory's excellent PlayStation 3 and Xbox 360 adventure game Enslaved: Odyssey to the West, which launched in October 2010, shifted 730,000 units worldwide by the end of March 2011.
Although the new figure is up from the 460,000 worldwide sales Namco Bandai reported for the game in February, the Japanese publisher will still consider Enslaved to have performed poorly it initially targeted a million sales.
Executives have said it failed to break out because it was released during a packed holiday season.
But despite its poor performance, a sequel hasn't been entirely ruled out.
Elsewhere Naruto Ultimate Ninja Storm 2 moved 1.1 million worldwide, and Dragon Ball: Raging Blast 2 sold 580,000.
Overall, Namco Bandai enjoyed a much better time of it during financial year 2011 than the previous year, during which it made a loss.
Sales were up 4.1 per cent, and operating income was up a whopping 767.3 per cent.
The PlayStation 3 was Namco Bandai's biggest platform. It sold just over 5.5 million units on Sony's console, a million ahead of the units sold on the PlayStation Portable.
The company sold just over three million Xbox 360 games, just under three million Wii games, and just under four million Nintendo DS games.
