After reading the reviews I was skeptical about buying this for the Wii, and at first I was disapointed. Once I got used to the controls however, I found myself thoroughly enjoying it. The graphics aren't great (it is a Wii afterall) but the new playing angle is fun and once you master the controls the game play is very fluid and works well. Personally I like that the call a second defender button and shoot button are no longer the same. Too often on the 360 I found myself calling a second defender only to tackle the ball and then launch it by mistake. To my knowledge the Wii version doesn't offer the ability to call a second defender, but the AI seems to do a pretty good job of sensing you're in trouble especially with the more skilled players you're defending. Trick plays and bending shots are also easier and more intuitive on the Wii version. Fixed pieces are much easier and have a higher success rate for scoring or picking out a player.
All in all, it takes a bit to get used to, but it well worth it.
