Before I start, there is so much right with FIFA09 that i fear that it may be tweaked too much next year. Please do not mess about with it too much as I feel it is almost perfect. Saying that, there are some things which need looked at/implemented. Here's my thoughts:
Pros from FIFA09:-
Custom Tactics
Need both players to agree to skip cutscenes/replays (love this)
Animations are awesome
Can see the crowd when playing (Tele - height down)
Collision System
Goalkeepers release ball quicker
Net Physics
Stadiums
Atmosphere
Faces (except eyes)
Ball Physics
Dipping volleys
Custom camera angles
Cons From FIFA09:-
Responsiveness (between button press and action happeneing)
Keepers dive dramatically when ball is trundling past them
Close control not as effective as 08
Through ball takes too long to charge up
Advantage rule flaws
Replay framerate
Replay angles (why always from below player?)
Those bloody "Lets FIFA09" signs next to goals (looks awful)
Super Cancel (player slows down when you pull out of run)
Weather issues (can't see rain, no weather in MM)
Players zombie eyes
Quick unranked match option (takes bout 5 mins to find in menu)
Player switching (can't switch to closest man quick enough)
Keepers still seem hesitant coming out when button pressed
Too many outside of the foot shots
Player movement doesn't seem free (still on rails)
MM mode issues
No replays of reason for booking after advantage has been played
First time shots (ball running toward oncoming player) should be far more powerful.
Tall defenders should not be marking posts at corners.
Half the team do the same stretching animation at the same time just before kick off.
Would like to see in FIFA10:-
Quick free kick
Real time cutscenes/celebrations/bookings etc
Longer replays
Highlights mode (ala Halo's Theater Mode)
Face Import (Tiger0
for all players (so I can put proper faces for generic faces or better faces for official faces - if possible)
Tall players automatically come up for corners
Choose whether to head the ball or volley it (it's fairly random just now)
Finesse button for outside of foot shots
Editing suite (PES)
Save replays to HD (EA Sportsworld sucks)
Quick select for set piece taker / lay off man
Set play creator
Correct fans celebrate goal (not just stand up and sit down)
If connection is lost during a game on live, say who disconnected/got cut off
The ability to save customs team line-ups and formations for online play.
Different net styles at different stadiums.
Be able to round the goalie.
The option to play online matches with specific settings (ie shooting semi and through balls manual etc) not just manual everything or assisted everything.
Create a celebration mode (I know some people hate the celebrations but i think they add something to the game)
Would love to see the cons sorted and the new ideas added
