The Lowdown: Doukutsu Monogatari -- aka Cave Story -- is one of the biggest underground successes in recent years. A free amateur game from Japan, Cave Story has quietly spread its charming 8-bit looks and brilliant but challenging Symphony of the Night-style action to gamers the world over. And now it may be coming to the PSP as an official release.
The Obstacles: There are a few logistical problems facing a PSP conversion of Cave Story, unfortunately. It was originally released for free on PC, and Sony may be loathe to publish a game that can be acquired freely elsewhere. Especially one with such simple graphics. Worse, the game's creator seems averse to the notion of his creation being distributed for a price. But if these issues can be smoothed over, this could be one of the PSP's greatest moments.
