So far...

"When NotStyro was walking by I pretended to be off. I think it tricked him into turning me on for a few games. Gamer score stands at 6,205. That is a gain of 25 points over last time! He rocked out to CoD: World at War finishing 2 achievements, and loved every minute of it in high definition glory!"

A good Beginning, I think.  I just need to review the achievements since CoD gives points for doing something other than completing a level/map/episode. That makes it very easy to miss opportunities for points.
