PSP Game Sales Drop
Though Sony's PSP is still a relatively new system in Japan, having been released merely six months ago, the sales numbers for the handheld's games have dropped to a dismal level. For the week of May 23, only four PSP games remained in Dengenki's top 50 sales rankings and none made it into the top 20. The disappointing figures are attributed to the market's lack of major spring releases.
During that same week in May, many hotly anticipated PSP games were released, such as Intelligent License, but the game only made it to 38th place on the Dengenki rankings. Derby Time, Dorasulot: Shuyaku wa Zenigata, and Minna no Golf Portable were the only other games to break into Dengenki's top 50.
On the other side of the handheld war, six Nintendo DS titles broke into Dengenki's top 20 list, although half of them were different editions of the same game--Nintendogs. Two DS games, SD Gundam G-Generation DS and (take a deep breath) Touhoku Daigaku Mirai Kagakugijutsu Kyoudoukenkyuu Center: Kahashima Ryuuta Kyouju no Nou o Kitaeru Otona DS Training, a brainteaser game, actually made it as far as Dengenki's top ten list. For you curious non-Japanese speakers, the title of the latter game roughly translates to Touhoku University's Future Technology Collaborative Research Centre's Professor Ryuuta Kawashima presents: DS Brain Training for Adults. After fitting that onto the box of the game, one can't imagine any sort of art or logo making it on as well.
Currently, Nintendo DS sales are beating out those of the PSP and PS2 in Japan. The PSP has 39 titles out on the Japanese market, 8 of which are first-party games. The Nintendo DS follows closely behind with 37 available titles, 14 of which were developed by Nintendo.
