In the FIFA 11 Lounge Mode, you can add up to four players from your own console only and play matches against each other. You can keep a running tally of things such as the games won/lost, goals scored/conceded, streaks, bookings, etc. This is a fun way to have a long lasting series of games to see who is the better FIFA player.
Another feature of this game mode is the ability to earn Badges. Badges are unique accomplishments such as "Hat Trick Hero" or "Stamina King", which you can strive to be the first in your lounge to collect and claim that badge to your name
