I recently decided that the number one most significant gameplay innovation of the last decade is the achievement system. You may argue with this, but I can think of no other concept that has more radically altered the way I play video games (not even multiplayer). There’s a certain aspect of revealing your entire body of gaming accomplishments that gently but persistently warps mind and spirit.
For example, back when my virtual conquests were a private affair, I could exercise a bit more self control regarding my gaming agenda. Let’s say it’s the spring of 2002 and I’ve got 200 spare hours of my life just lying around. If I decided to use those hours to drink beer with my friends and/or have sex with my girlfriend, no one needed to know I did so in lieu of power-leveling that little bitch Tidus enough to take on the secret Final Fantasy X boss Nemesis. Moreover, since there was no public record of this decision... who knows what really happened? With enough time and self-delusion... maybe history holds that I did defeat Nemesis after all.
In the Age of Achievement we have no such luxury. Now all our triumphs and failures are laid bare for the world to see, and I believe such exposure gives game designers a disturbing power over the way we play video games. To emphasize the seriousness of this issue, I thought I would list the top five most perverse behaviors I’ve been driven to by the quest for Gamerscore.
