Where's the fun in burning through a game days after it is released? I know many of us have played FF7 before but it's still a fun game, trophies are meant to extend the life of a game not suck all the fun out of it and turn it into a speed run.
The game has a 3x speed option and another option that instantly refill limit gauge, HP/MP every time its your turn. Its not impossible to see how it was done so fast.
