The, it's not that the game is total crap, but this isn't ever going to become a rare or pricey Atlus game.
I scored a used copy on eBay 2 weeks after it came out for like $16.xx shipped. It's sort of fun in a way, especially if 2D 1st person view dungeon crawling jRPGs are yout thing (for whatever odd reason that would be).
If you can get it for $10 I say go for it. Magical Starsign & Children of Mana were $15 a week ago and those games are quite a bit better.
