This is a new, factory sealed Brain Trainer Portable game for the Sony PSP, imported from Japan. It is rated E10+ and falls under the educational genre. The game was released in 2005 and is part of the Brain Trainer video game series published by SEGA. This unit is in NTSC-J format and is a great addition to any video game collection. The package includes one unit, and as a US seller, I am ready to ship it out to you as soon as possible.
