Its not really so much that this particular game bombed, its that generally most PSP games don't really do too well in comparison to all other systems. That's the sad truth about the PSP. The hardware does pretty well, but the software sales are terrible.
Don't call me a fanboy or anything (I don't have a DS or PSP). I've even boughten several PSP games and a PSP system over this past year (for my gf), I currently have Tales of Rebirth(PSP) pre-ordered (release is next week).

Me since the games were revealed, the fanboys since E3."
