Football manager 2009 (SEGA, 2008)
When Sports Interactive and SEGA released Football Manager 2009 in November 2008, it featured over 5,000 playable clubs from over 50 countries, and at least 370,000 players and staff from around the world. So comprehensive is the Football Manager database that Sports Interactive believes it has accurately predicted the rise of several world soccer stars, including Argentinian wonder-kid Lionel Messi, who top-scored in the 2008/09 UEFA Champions League playing for Barcelona.
