Disgaea, La Pucelle, Phantom Brave are all made by NIS. However, Disgaea was published by Atlus and La Pucelle was published by Mastiff because at that time, there wasn't a NIS division in America. After Disgaea's sleepy hit and sort-of-well-received La Pucelle, NIS Japan decided to open their own division in America. They produced a whole buch of copies for Phantom Brave, thus explained why the value tanked. I'm not a collector so value doesn't mean a thing to me. As long as I can get to play the game I want, that's all it matter.
