This is a really fun game, even if you aren't all that into football/soccer. The commentary is realistic, there are lots of stadiums to choose from, countless teams, fantastic formation and substitution options, lots of different modes like tournaments, leagues, custom leagues, training etc. The gameplay is good fun, you can score some excellent goals and there is a huge variation of skill moves that can be easily mastered.
On the negative side, the AI of the players is lacking slightly (they seem to act like robots) and the graphics don't do justice to the Dreamcast, visually this game is more like an N64 game, with the players being rather square. The surroundings are good though, and the game still has a fairly realistic feel. None of this really takes away from the game.
To sum up, this game is fun, and at such a low price it's hardly not worth buying. Get it!
