The PSP version of Echochrome costs twice as much as the PS3 version, but Siliconera explains there is reason for the extra money. All of the answers are found over at Impress Watch (Japanese).

The PlayStation 3 version is actually "Echochrome: Jokyoku" or "Echochrome: Prelude" in English. For 1,800 yen ($17) you get a get a sample of Echochrome by tasting 50 puzzles. The 3,980 yen ($37) PSP version contains 100 puzzles and multiple modes including a variation where you have to avoid walking dark echoes.

Fortunately, both versions come with canvas mode, which lets players create and upload puzzles on the PlayStation Network or transfer data via the PSP's Ad-Hoc mode. With this new information the PSP version is more tantalizing. However, the cheaper PlayStation 3 version supports users-created content, which devalues the addition of the extra 50 puzzles.

Siliconera reports: "At the Taipei Game Show, Sony draped the curtains on a limited edition PlayStation 2 set to arrive in stores on February 4 in Asia. The new color, Aka Takara Kurenai, or (loosely) Crimson Red Treasure comes out just in time for Lunar New Year. While it superficially feels like the PlayStation 2's days are numbered since the PlayStation 3 is on the market, Sony's most popular console keeps chugging along.

Speaking of the PlayStation 3, Echochrome has a spring 2008 target in Asia. That's no where near as solid as the March 19 release date for Japan, but Echochrome is starting to blob around the world. Perhaps, Sony will announce a solid NA release date at Game Developer's Conference".

Echochrome is down for release sometime in Q2 in Europe, Sony UK said this morning in response to rumours that the PSP and PSN game is set to launch in Japan on 19th March.

Siliconera reported the latter recently, adding that the price has not been set but that it will "probably fall in the USD 25-30 price range" on PS3 given the PSP version's 3,990 yen price-tag.

Last week Spencer mentioned Echochrome was arriving on the PSP on March 19. Now he can confirm it will arrive on the PlayStation Store as a downloadable PS3 game on the same day. The price has not been announced, but if Sony is selling the PSP version for 3,990 yen ($36) it will probably fall in the $25-$30 price range. Details are also hazy if the PSP release contains the same puzzles as the PlayStation 3 version or if you can play the PS3 release on the PSP via Remote Play. That would be an awesome idea and we'll find out soon when Echochrome arrives in Japan.

20th Dec, 2007 Gaming is an up and down experience. Some years cram top quality titles into our every orifice until were bursting with videogame joy and have excess polygons dripping messily out of our ears, while some other years… Well, some other years are 1983. In 2007 though, weve had a very good year indeed. A scarily good year in fact. One which has provided us so much brilliance on every format that its a genuine worry that the laws of karmic balance will soon bring us a plague ... » Read More

As we revealed earlier, you can already play a game very similar to the recently announced PSP and PS3 Network game Echochrome right now, for free from the internet. Just in case you can't be bothered to hit this link and try it for yourself, we thought we'd show you what it can do. It should be noted that this is really just a tech demo to illustrate the strange concepts of subjective landing and subjective existence, and not actually a game at all. But here's the problem - the demo is fun ... » Read More

Remember how Valve Software announced Portal and it subsequently emerged that a project that inspired the puzzle game could be downloaded from the 'net?

Well, a similar thing has happened with Sony's Echochrome, it's a PSN/PS3 puzzle game that was announced at E3 that's based on the manipulation of 3D objects that make up each of its levels. The idea is to guide a matchstick man to safety.

OLE Coordinate System, which you can download now for PC, features a very similar concept and has presumably inspired Echochrome.

[UPDATE] While we're not backtracking on our opinion that Echochrome has the potential to be one of the sleeper hits of the PS Network, we've just found out that the game was far from Sony's "original" idea. The game has existed as a tech demo for PC here since last year, described as an "interactive optical illusion" and coded by one Jun Fujiki. It appears Sony has been given permission to develop this free game for the PS Network, only with preset levels - the downloadable version simply ... » Read More

Sony's annual E3 press conference opened with what could have been the biggest reveal of the entire show if it hadn't been leaked last week: the new $499 price of the PS3, as well as the introduction of a new $599 model that comes with an 80GB hard drive and a copy of online-enabled dirt racer Motorstorm. This left biggy-wig Jack Tretton (who began the event speaking through his character in the PS3 virtual world Home) to launch right into the publisher's game-centric, four-part ... » Read More

During the Sony press conference at E3 Phil Harrison announced a number of games that stood out. One of them was an abstract puzzle game.

Called Echochrome, the downloadable game is made by Sony's Japan Studio. Graphics play a very, very small role.

The overall goal to the game is to get from starting point to the end point. Throughout the later levels there are pitfalls, teleporters, and bumpers that will make each level more challenging then that last.

It's unknown when Echochrome will be released but it will be one of the 180 PSN games Sony will be releasing worldwide before March 2008.
