Having sold 217,000 copies on the very first day, the new Japanese chart-topper Phantasy Star Portable went on to ship 500,000 copies in the first week. Though it won't beat out reigning champion Monster Hunter Portable 2nd G's figures of 880,000, it did beat out another very popular PSP game with a larger fanbase: Crisis Core: Final Fantasy VII. The Square Enix game managed to ship 480,000 copies in its debut week.
