For those looking for a hard copy of Echochrome on the PlayStation Portable, now might be a good time to start checking Play-Asia's stock. LevelUp was able to exclusively confirm that when the game comes to North America, it will only be available as a digital download via the PlayStation Network. The game is currently available on UMD in Japan and Asia.
We recently ran our own review of Echochrome for the PSP, and our reviewer -- the illustrious Brad "Dick McVengeance" Rice -- liked it so much he gave it an 8.5, branding it with our "Buy it!" stamp. I actually spoke to one person yesterday who said that they imported the game based on that review alone -- did you?
No word on when Echochrome will make its way to North America, but I hope it happens before I break down and import it myself.
