Tomorrow, Microsoft' Xbox Live service will have 5th birthday with more than eight million members.

To celebrate the anniversary, Microsoft is giving all Xbox Live users the opportunity to download the XBLA game Carcassone free of charge between 12:01 A.M. PDT on Nov. 15 and 11:59 P.M. PDT on Nov. 16.

Also, every active member who joined the service in 2002 will receive 500 free Microsoft Points.

"In just five short years Xbox Live has revolutionized the way friends and family have fun in the living room," said John Schappert, corporate vice president of Live, software and services at Microsoft.
