"FIFA 09" features a revamped collision system and an option for 10 versus 10 "Be a Pro" online matches, and the new "Adidas Live Season" feature, which updates all the players' stats in a particular league based on the player's form in real life. Although the feature is activated through microtransactions, gamers have access to one free league of their choice from the moment they activate the service to the end of the 2008–09 season. Online play has also been improved in "FIFA 09", with a feature called "FIFA 09 Clubs" allowing players to form or join clubs and field their strongest team online. The game is the first in the "FIFA" series to feature user-controlled goal celebrations. "FIFA 09" has met with generally positive reception from reviewers.
