Well Xbox Live cheevos is a whole other level than Gamification.  You really can't compare the 2.  Xbox live more than just games.  There are some Kinect apps that are not really games that have cheevos, plus there might come out with other apps.  The apps like ESPN show up in your games played, but no cheevos for it.  It's just a matter of time.  It's very hard to talk to people with less than 20,000 gamerscore.  They just don't understand.
