I remember playing VII non stop, did everything there is to do in the game...
ok it was my ONLY PS1 game at the time :P
Ruby Weapon and Emerald Weapon were tough and the rewards you get for killing them were not really all that great. I received a gold chocobo for killing the one, but a gold chocobo is needed to get the best summoning in the game and you cant kill them without it... kinda defeats the point if you ask me...
