Dude most chose sony cause they offered the best deal not cause FF was coming out for it. Saturn was much much harder to dev for then PS, most devs simply had no idea how to program for it. Saturn was a pain while N64 was held back by cartridges.
For most there was only one option, and Sony capitalized on it.
FF was not that big until the 7th one on PS, you could turn it around and say PS made FF what it is today. Highest non PS ff was only 3.4 million, PS tripled that.
