Since 1995 when I bought Int Superstar Soccer on SNES but this was not the prequel to what we know as PES as ISS on SNES was developed by KCEO.
On PS1 before ISS Pro 98 there was a game called Goal Storm which is the true prequel to PRO games on Sony as it was developed by KCET, and was released about 15 months before the first KCET developed ISS Pro on Sony.
Goal Storm was a pretty poor game but the great PRO playability soon to grace the world was evident even at this early stage...
P.S - I am used to calling PES, PRO.
