This newer game is by far the more impressive choice, with fully fleshed out features, excellent animation, solid soccer gameplay, and an exciting presentation, replete with another batch of great music from around the world. [Jun 2006, p.112]
If you have FIFA from last year, and you're not worried about having the official World Cup Germany licensing and such, or the new Global Challenge mode, then there's isn't that big a reason to upgrade as the gameplay is pretty similar.
The Cube doesn't feature the stadium tour video extras of the German venues or the nifty stadium fly-ins that the other platforms feature, but on the field you won't notice much of a difference in terms of gameplay.
The lack of an online tournament mode did not go unnoticed and it's something that needs to be addressed in next year's version - and considering how good this game is, you can be rest assured the series will continue.
As a standalone football game without all the World Cup-related fluff and filling, EA have provided something which is actually good fun to play (both off and online), certainly not like their frustratingly average efforts over recent years.
Surely everybody knows the score by now: EA ever so slightly update FIFA. It gets new stats, new players, new kits and slightly better graphics whilst remaining pretty much the same game it always has been.
All of the things EA did right with FIFA World Cup 2006 are overshadowed by the simple truth that what should be the most fun part of the game -- having exciting scoring chances -- is completely negated by shoddy game performance near the nets.
