I've already beated the game hundred of times, even without the use of materia. I guess Ruby isn't all that hard...I only tried him out once a couple of years ago
Maybe I should try him out again, I've done everything there is to do in FFVII except defeating Ruby weapon, so, maybe I should give it a go.
The reason for my reaction, were simply because the one time I fought him I remember getting my ass kicked around.
