I realize there haven't been a whole lot of PSP deals the last week, but I have a real doozy for you today. The Asian import version of Gitaroo Man Lives, a rythm-based game, is available for a measly $20 from Play-Asia. And to make it even sweeter, the it's only $3.10 for world-wide shipping.
If you've never heard of the game, it received an 8.8 from IGN, and they said it's "one of the finest games the genre has ever produced." Ya hear that? The game is awesome, folks, so hurry and pick it up before they're all gone!
