i cant decide, secret of mana and ff's for the SNES were apparently amazing, then on the PSX, some say they were crap, some say good. I guess graphics and gameplay on the PS2 and nice gameplay on the cube....
As long as they have a good story line it isn't gonna matter what system they're on. While GCN has slightly better graphics, Sony will keep right with it when it comes to play control. Another reason I think FF should be back on Nintendo is that Nintendo is where it started, and I think it should be on Nintendo until it ends.
