Pro Evolution SOccer 2009

Gameplay
Gameplay has been changed for Pro Evolution Soccer 2009, with key additions to the Teamvision system, tactics change according to situation, off-the-ball fluency AI recognizing strategies that works accumulating data on an ongoing basis within Master League and League modes. Another new addition is the readjustments for ball movements. PES 2009 has new air resistance calculations for the trajectory of the ball. There are also new friction routines to affect ball movement in terms of ground conditions, backspin routines are calculated so that ball slows accordingly, and the bounce of the ball can be used more effectively: players can flick the ball up to tee a shot, or to lift it over a defender's trailing leg. If a player has the ability, they will be able to perform skillful turns. PES 2009 also features a new game mode called 'Become A Legend', much like 'Be a Pro' from the EA Sports FIFA Series.

Generic Teams
There is also a separate league with 18 generic teams (Team A,Team B etc.), which can be edited fully, like in the previous game. This is thought to be due to the fact that Konami failed to get the rights to the German Bundesliga, and is usually made into the Bundesliga or another league of one's preference by patch makers. However, most people use this to put their edited players into playable teams from the start instead of having to play through Master League to purchase them or alternatively edit the existing non-generic teams. This feature does not appear in the PS2 version of the game.

Wii version
Building on the control system of its predecessor, PES 2009 expands on the basic concept of players controlling both the player with the ball and those around them.

PES 2009 for Nintendo Wii will feature a number of key additions, with an enhanced shooting system offering more control. The development team has also reworked the defensive elements of the game, with more control over defenders and more ways to close down attacking threats. A new AI system has also been implemented and results in more sophisticated and intuitive movement from team mates according to the player's commands.

The Wii version was released on 31 March 2009.
