Overall the game has certainly been improved and does make for better playing. You would be right in arguing that not a great deal has really changed with certain annoyances from previous years continuing to be added. However, if this is your first time in thinking of getting the game, then this is certainly the year to go out and buy it.
For those who do buy the game annually you are more likely to appreciate the improvements that have been made than those who don't. Let's see what they have in store for next year. Arguably, FIFA 10 is the best edition yet!
