Kingdom Hearts: Birth by Sleep provides good value for your money. Slashing through all three story strands may take you 25 hours or more, and the command boards and additional modes provide reasons to return once you've left the story behind. It's unfortunate that Birth by Sleep relies so much on repetition and that a few foibles from the series remain largely untouched. These and a few other woes hold this PSP exclusive back from greatness, but vibrant visuals and snazzy, evolving combat will likely charm fans and newcomers alike into forgiving most of the flaws. Birth by Sleep harbors few surprises, but it's a fun and comfortable addition to a quality series.
