Your troops die permanantly in Tactics Ogre if they die and turn into a card/treasure without being ressurected or the battle being beaten before they turn into a treasure or a card. I thought final fantasy tactics was the same way with the crystals?
Phantom brave and all those other games were made by the same person, but I haven't played the others

I just know I got kind of tired with some aspects of phantom brave. I did enjoy some parts of it though.
