Just beat it (with the B ending, fuck that Alissa cunt I WON'T DO WHAT YOU TELL ME). Really enjoyed it despite not liking the other Dept. Heaven games. Was easy pretty much the entire way through except the last two fights, but this was on Normal difficulty, so if you're a difficulty nut you might wanna play it on Advanced.
Story was generic as far as SRPGs go, but still pretty enjoyable because the characters are pretty likable (for the most part, a couple of the main ones are incredibly bland). Ending B fucking blew but I'm debating doing NG+ and getting Ending A to see if it's any better. Gameplay was enjoyable once you get used to the different systems, but like any other Sting game it's a bit much to take in at first. Even if you didn't like other Dept. Heaven games I'd say this might be worth a try, it plays more like other SRPG games like FF:T or Tactics Ogre (though there's no real character development in this, it's just managing equipment). Dunno if it's worth full price though.
