Although it looks like a simple game, it is really enjoyable and addicting. Along with football/soccer, you also play the life of a football/soccer player. The reality has been implemented via several things such as losing energy while going to play away, not ignoring the girlfriend, making the papers due to sensational events, earning from horse-racing more than football/soccer. So it has a pretty comprehensive content.
In the game, there are also some events irrelevant to reality like the Premier League championship of a team that have actually never been in the top places of the league, the quarter-finals of UEFA Champions League's including at least one team that actually join to the earlier qualification rounds of the tournament, German National Team's scarcely qualifying out of the qualifications for UEFA European Championship and FIFA World Cup... But these add spice to the taste of the game. :)
