PSP Echochrome costs twice as the PS3 version

Fans of quirky puzzle games have something strange to chew on. The PSP version of Echochrome by SCEJ costs twice, compared to the PlayStation 3 version of the game. As it turns out, the game UMD costs JPY 3,980 (about US 37), while Echochrome for Sony's next-gen console is only JPY 1,800 (or US 17). Of course, there's a reason for the price difference other than the fact that one is stored in a UMD, while the other is downloadable content.

Thing is, the PSP version contains 100 puzzles, as well as many different modes of gameplay (one of the more notable game modes require the gamers to avoid walking dark echoes). On the other hand, the PS3 version - named Echochrome: Jokyoku or Echochrome: Prologue - is just a sample of the full game, with only 50 puzzles.

Both versions do have the canvas mode, however, which basically lets gamers come up with their own user-created puzzles.
