FIFA 21 is a soccer simulation game developed by EA Sports. The game features a wide array of teams and players from leagues around the world, and allows players to compete in matches against each other or against AI-controlled opponents. The game includes several game modes, including a career mode where players can manage a team and compete in seasons, and an Ultimate Team mode where players can collect and trade player cards to build their own dream team. FIFA 21 also introduces a new gameplay mechanic called Agile Dribbling, which allows players to have more control over the ball and perform more realistic dribbling moves.
