Pro Evolution Soccer 2009 is a realistic football game from the Pro Evolution Soccer video games series that integrates real-life football stars into gameplay. This Microsoft Xbox 360 video game is controlled with a D-pad and analogue stick, which allows the players to perform feints as well as a wide array of tricks. The environment of this sports game is realistic because the ball is affected by physical factors, such as air resistance, weather, and ground friction. Moreover, in the Masters League, the player's performance changes according to his mood. In the Become a Legend mode, the players can go through a football player's career, starting as a rookie striker or midfielder and becoming a professional in the end. It is also possible to play in the gamer's favourite attacking position with one player as opposed to controlling the whole team. The Become a Legend mode allows the player to compete online with friends. These computer-controlled teammates benefit from enhanced artificial intelligence. This game is rated G by the Australian Classification Review Board (ACRB) and is suitable for all players.
