And it would have outsold all of the competition combined if it weren't for that pesky Xbox 360 contributing 1,547 units to the tally. The number the other systems had to defeat was 129,986, the number of PSPs sold in Japan last week according to the compulsive counters at Media Create. Nintendo's DS occupied the second place in the chart with 58,916 sold -- less than half of that managed by the PSP.

The system's monster success arrives hand-in-hand with Capcom's Monster Hunter Freedom 2 G, which sold 880,468 copies in its first week. Capcom revealed earlier this week that it had already shipped over a million units of the PSP expansion in an attempt to satiate the demand for "epic battles with giant monsters."
