Just a couple of suggestions:
1. Game Speed - Allow for different speeds within the game (During Match). At the moment it all seems just a little bit too slow.
2. Game time - Allow each match to take a certain amount of time (e.g FIFA - 2 minutes halves, 3 minute halves etc.)
3. Have global news announcements for big transfers - e.g. Ronaldo to Real Madrid should have an announcement on my personal page.
4. Increase starting rating to 6, decrease amount of rating lost due to not being passed ball (e.g. If I start as a sub in minute 80, and don't touch the ball, my rating will be a four... I havn't done anything, so should be average?)
5. Better match engine - too many long balls, too big a gap between midfield and attack, strikers never pass the ball sideways when a teammate is in a better position)
6. Description of 'Advanced Dribbling' under help on match options
7. Better sponsors - It is possible to get sponsor percentage without sponsors, and sponsor random events without also.
8. Hotlinks - Clicking on players should allow you to go to their page, with their stats etcetera.
9. Player History - Each Player should have his in-game history available.
10. Manual - A PDF or other for the game
11. Option to look for a girlfriend/ go clubbing/ more relationship options.
12. Special Relationship Options - Christmas, Birthday etc.
13. League Specific Transfer List - View Transfers in each league under competitions panel.
If I think of more, I'll put them in. Otherwise, feel free to add more.
