You probably are familiar with how Netflix works, but did you know you could get a similar service for video games from GameFly?  Right now you can save up to 20% when you get a 1 year gift certificate (nothing wrong with giving that gift to yourself if you want).  GameFly lets you play games for as long as you want, and then trade in for the next new hot game.   This service allows you to always have new games to play and not a bunch of games you have played to death.  If you want, you can also click here to get a 10 day Free Trial for Gamefly.
