PSP Hyper reports that videogame retailer blog Sinobi reports that 350,000 copies of Dissidia Final Fantasy were sold last Thursday, when the game went on sale in Japan. The number include the super nice 20th Anniversary Limited Pack that come with a special edition PSP, which is around 40,000 units according to Sinobi. It worth noting that Crisis Core: Final Fantasy VII also did 350,000 copies on its first day and went on to sell almost 490,000 copies in its first week. Monster Hunter Portable 2nd G still has the best first day for a PSP game when it sold 670,000 copies earlier this year (MHP 2nd is second with 512,000).
