Sony's much anticipated Vita title Gravity Rush saw solid sales when it released in Japan last week, but its strong debut wasn't enough to push sales for the recently-launched handheld.
For the week ended February 12, Gravity Rush was the second best selling title overall, with 43,462 units sold, according to Japan's Media Create (this data does not include digital sales via PlayStation Network). The PlayStation Vita itself, however, sold only 13,939 units, down from 17,141 units the week prior.
These low sales are just the latest in a continuing struggle for the PlayStation Vita. The platform hasn't gathered much momentum since its launch in December, often selling less than its seven-year-old predecessor, the PSP.
That pattern resumed this week, as the PSP sold 15,860 units, putting it just above the Vita on the hardware charts.
The PlayStation Vita will officially launch in North America next week on February 22, and reviewers and other publications have expressed divided opinions on the potential success of the platform in the West.
In contrast to the PlayStation Vita, however, Nintendo's 3DS continues to maintain a strong presence on the Japanese charts, holding its lead as the top-selling hardware last week and claiming four of the top 10 spots on the software charts with Resident Evil: Revelations, Mario Kart 7, Monster Hunter 3G, and Super Mario 3D Land.
Looking at the Japanese software charts as a whole, Konami's newly-launched PSP RPG Suikoden: Tsumugareshi Hyakunen no Toki was the week's best selling title with 61,784 units sold.
Following its disappointing launch the week prior, Namco Bandai's Soul Calibur V fell to number 11 on the software charts and sold only 7,896 units. Notable titles such as Final Fantasy XIII-2 and Tales of Innocence, meanwhile, fell off the charts entirely.
