Yeah I really hate random treasure chests. They pulled this crap in FFXII too which is just crap. In online games like XI I get it since you can't just have one chest for one person to open, but in one player games it's just silly and a cheap way to have replay value.

Edit: Oh yeah I'm Quina. Uh, I EAT YOUR BOMB FRAGMENT. *learns Self-Destruct*
