I can't say that I won't be looking forward to ISS3, but right now, I'm quite impressed with FIFA2003. I am aware of the annoying problems and idiotic limitations, but the atmosphere in the game is really suberb, and with adequate gameplay FIFA2003 is quite enjoyable. I can score from outside the box and crossing&headers are not rare, and since editing access forms and Shlomy's superb flags came about, I'm hyped up about playing. FIFA is fun, when I play PES or ISS, I really concentrate on the playing, which is rewarding, but in the long run, not that fun.
When the game works well enough not to annoy, and gives some really superb moments (tricks and any nice goals and such) with one end of the crowd singing "two-nil, two-nil, two-nil" and the other "are you man united, man united, man united in disguise?" I could care less about worrying about the fact that the players don't have enough self-esteem to head on their own.
