1 - Improved database, for example it would be nice to have the REAL German and Japanese National Teams(although not likely to happen, Germany rights owned by EA, and Japan's owned by KONAMI). Or, the player that replace them should be available to transfer. One of the German strikers annihalated Italy at the World Cup, scored 4 goals, stats were brilliant aswell.
2 - Better skins. A dark skin with contrasting white/light colours, and also a light one aswell for those who like that sort of skin.
3 - Following the above, maybe a customizable skin, so you can adapt it to the user's needs. Being able to adjust the layout of certain pages would be nice, as some on FM09 are a little messy and unorganised.
4 - Request a new stadium. Stadium building isn't the manager's job, so this would be the next best thing. For example, I took Darlington to the Premiership, and had the smallest stadium in the top two divisions, and it was extended fully, so it meant I had less gate reciept money coming in.
5 - Would like to see bigger improvements on the 3-D match engine, maybe making the graphics better, aswell as some stadium effects, not just a grey shape around the pitch.
6 - lose the -10 PA, replacing it with a undetermined PA, meaning the player can be world class with the right training, or a flop with the wrong training. After all, I think there is around 10-15 original(not regen) players with a -10, and a few of those are already with big clubs.
7 - More in depth scouting
8 - the ability to sign players directly to a foreign feeder club, so you can surpass the Work permit problems found with some prospects in S America/Asia/Africa.
9 - Also, if you have a few leagues in your game(I have 18) maybe the game should only visibly process the results from the league that you are currently managing in. Sometimes, I have to wait 15 minutes for the results to go through.
This is what I would love to see, but FM2010 will be great.
