I have played this with my Brother and our kids, and it is great fun. The controls take a little getting used to, but once you do you can have some great games. The set pieces play well once you get used to them and the match play works fine.
The screens are easy to navigate around and the design is unclutered.
The graphics are pretty decent, basically what you expect from the Wii, after all it isn't anywhere near as powerful or well spec'd as the PS3 or Xbox360, but they do the job.
The main thing is that it is fun for us all to play and the kids enjoy it especially.
(I have Fifa 11 on the PS3 for us adults to play and it is a totally different style of play, much more serious and realistic.)
I will close by saying that if you want a fun arcadey footy game that lets you just get on and play, then it is well recommended. If you want something more in depth and complicated, then get Fifa 11/12 for one of the other consoles instead.
