If only there were some way to show everyone that you rock at videogames... Oh wait, there is!
Back in the '80s, arcade heroes got to enter their initials in the high-score list. There's a modern-day equivalent on Xbox 360 consoles: the Achievement score, a tabulation of points earned for all the games you've played. Other Xbox users can see it in your profile, and some "achievement whores" cultivate that figure the way Facebook users bulk up their Friends list. Rent these titles at Blockbuster to boost your score.
