10. Pro Evolution Soccer 5 (PC)
The series has fallen from grace lately (while at the same time FIFA has improved), but in the mid 2000's PES was the premier football game, and it's PES 5 that I always thought was the best. Other than the perfect gameplay, it was always the Master League that helped it surpass its rivals (nobody else has come up with a better mode to date). That's where you take a club from the lowest division all the way up to greatness, developing players as you go to the point that you may have a completely different squad from what you started out with. It was that good, that it was my go-to game when I had nothing else to play at the time.
Number 9 was a revolutionary step within the series.
