I have to agree with Breath of Fire: Dragon Quarter.
Insanely hard to go through without busting your Dragon Meter thingy. I never used it last time i played and it took hell of a time to go through bosses.
Thing is, if you have power in that game but you're tempted to use but can't because you die if you rech critical limit, then why have it at all? Why didn't they make Dragon Quarter with the same Dragon system they used in BoF3? Just mix 3 essences and get behemoth lol.
