So I got the PS1 version of the first game. It costed me $30 and appears to be complete (Gamepro stickers? Why?)
But I also notice, in very fine writing below the cover title:
"Ogre Battle Saga
Episode Five
The March of the Black Queen"
... Episode FIVE?!?!?!
According to Wikipedia, there was never an Episode 1-IV, so what gives?
