FF2 the one where you get your HP up by getting it less than half after a battle? That system was confusing, but if that's the one, then I was at max health for all of my characters. I think.
FF2 was the one that i think was best, if you get hurt, your HP and stamina will increase, fight more, strength increases, use magic, magic increase and such, i love that game, my last playthrough had about 6000-7000 for each character...more than the final boss if i remember right. (yep, final boss has 15000, 6000X4 is 24000 minimum.)
basically that game doesnt tell you that a black mage cant use a heavy claymore or that massive hammer, it makes it look like this person could be a good make or a great fighter, but you can make anyone do anything in that game, i am almost done making my 4 people into friggin spartan soldiers...
