From my JRPG collection probably Hoshigama, a tactical JRPG from Atlus that was a spiritual successor to Tactics Ogre and came out at the end of the PSone's life cycle. I had never heard of the game when I saw it brand new at an EBGames and bought it, and haven't heard of it since.
Sounds like a winning combination, but it was a bit too brutally hard. Not only was a soldier dying permanent like in Tactic's Ogre, but the only place they gave you to train new ones also had the same risk of permanent death. I plugged the CD into my PC emulator so save states helped a ton, but even then I got to an early-mid game point where I hit a complete wall and couldn't proceed because in previous levels I didn't bother setting up this combo thing to kill enemies and get better item drops from them, and the standard top of the line item shop equipment my army was equipped with was completely outclassed by what the enemy had. It would probably be a great game if it wasn't so god damn cruel.
