I have a CDR copy of this game, it's a VERY good fighter, it's a 2.5D cel shaded fighter that uses polygons instead of sprites, but the characters are 2D looking, the backgrounds appear 3D (like CvS2), great animations and music, wild looking characters, there's a semi chun-li clone, and a jubei clone from SS, actually GREAT combo system, everyone has normal fighting game specials and supers, you also have a "music" super, where the screen turns into a bust a groove style interface, and you gotta pound out the rhythm bubbles on the pad to get the full combo, i made a combo video for this game once, some people have up to 28 hit juggles, it's almost as crazy as X-men vs SF with the air juggles. Everytime I try to mention this game to someone, they don't have a clue what i'm going on about.
It was also re-released under the greatest hits label in Japan for PSX. NCS had the re-release in stock for 38 once, but i was broke.
i've always said this is one of the best fighting games on the PSX hands down.
