Japan game charts: July 31-August 6

The Japanese gaming world was rocked this week with two monumental revelations: The best-selling game of the week was not for the Nintendo DS and Brain Age has finally left the top 10.

SD Gundam G Generation Portable for the PlayStation Portable, the latest game based on Bandai's Gundam anime franchise, was the best seller of the week, according to the latest data from Media Create. The top slot during the last several months typically has been claimed by a Nintendo DS game, with an occasional PlayStation 2 offering stealing a week on top here and there. Still, the anomaly will likely be brief. Five DS games remain in the top 10, with New Super Mario Bros. threatening at number two.

Another new game to the top 10, Jissen Pachi-Slot Hisshouhou! Hokuto no Ken SE, racked up high sales and came in at number three. Jissen Pachi-Slot is based on a Japanese slot machine, itself based on the Fist of the North Star manga series.

As well as those new titles sold, the performance of another new game was perhaps more notable for missing the top 10. Nintendo offered Japanese gamers a mix of action and strategy in Star Fox Command, but those who took the publisher up on that were only enough to make it the 14th best-selling game of the week. Meanwhile, Brain Age: Train Your Brain in Minutes a Day is showing signs of slowing down. The game has sold 4 million units worldwide--including 3 million in Japan--but this week it missed the top 10 cut, sliding to number 12.
