I personally love this game and still play it all the time. :)
The Pro Evolution Soccer series is renowned for its realism, and Pro Evolution Soccer 6 is abundant with new gameplay additions. Player AI has been massively upgraded, with players running intelligently into space when not in possession of the ball and pointing where they want the pass placed to continue the attack. Similarly, the physical side of play has been refined, with players working to turn a defender as they receive the ball, while defenders must learn to stand off slightly to prevent such moves.
- Dribbling the ball is now easier but the quality of your passing & shooting depends on the position of a players body in terms of accuracy & power.
- Opponent and team artificial intelligence has also been greatly increased, to the point where every man on the pitch is thinking independently.
- Apart from the animation, the graphics in general have also been upgraded with much better player likenesses.
- Pro Evo 6 plays a much more attacking game than previously, with counter attacks after a fluffed shot on goal made much easier than previously.
- The game simulates an unofficial international tournament, including both qualifying rounds and the finals.
