Kind of hard to describe... I owned a copy long ago and traded it in without getting too far. It's a strat-RPG, but not quite like FF Tactics or Tactics Ogre.
If you like Atlus' other stuff, it's a great game to pick up, or if you just want a unique RPG to play. One can only take so much Final Fantasy before it just gets disgusting.
I would recommend it. I will have some interest in that auction, myself...
Sorry about the NPB, man. And on a really rare game like that! Talk about a missed opportunity...
