This is a dramatic improvement from previous run of the mill tournament games such as FIFA World Cup 06 and Euro 2008, it only improves slightly on FIFA 10, but it was enough of an improvement to buy it because for me personally, I wasn't a fan of the changes to FIFA 10 from FIFA 09.
The best thing about this game is the options available such as Online FIFA World Cup mode which allows you to play as your favourite nation against others online, resulting in an overall table depending on how successful fans are of each country (at the moment Mexico top it by a long way, somehow). This gives you a sense of pride in playing your home country against another players home country online, making victory all the more sweeter if you're English and beat a German player.
Graphics are generally the same, and play has been slightly changed, only slightly, to make life easier for beginners - which is a good call by EA as they clearly knew that casual gamers would be buying this for the World Cup hype.
Penalties have changed whereas you can hesitate as you run up to the ball, confusing the goalkeeper, but this has generally been made too difficult, it's a lot harder to score a penalty than previous FIFA's.
The only gripe I have is in reference to the non existant Online co-op - unfortunatley it's only 2-player vs. - it would have been SO much better if a 4-player co-op etc could have been incorporated, whereas 2 mates online could play England, and 2 other mates online could play Germany - for example.
Overall though, quality game, it'll keep you going until FIFA 11, sure the price could of been a tenner of at least, but the game in it's own right is packed full of options for it not to run stale.
