[casual_games] msn game badges

[Jonathan Tonkin]

Hello, I really like the badge program utilized in MSN games. Does anyone have any data on how this prolongs user lifecycle and broadens the variety of games played? If you can suggest sources or firms with experience developing game centered rewards, education or advancement-type programs please feel free to contact me at, jtonkin at riptown.com.
 
Best regards,
 
Jon
