Raging Blast 2 was released in Japan 11 November 2010, which means that we now have some first-week sales figures for the game. It managed to grab the number-two spot this past week, selling 47,610 copies on the PS3 (the Xbox 360 version does not appear anywhere within the top twenty performing titles).
There are a couple different ways to look at this story, though.
Sure, it was the second-best-selling game of the week in Japan, coming in only after the Tactics Ogre PSP re-release. On the other hand, it sold over 10,000 less copies than the first Raging Blast sold one year prior (57,972 copies, all also on the PS3), despite a significant upgrade in many areas, as well as including Plan to Eradicate the Super Saiyans as a viewable feature.
