Back when I was playing World of Warcraft, we had an amazing GM (guild master, or in this case mistress) who played well, often, and with a level of intensity I never achieved, even in my most enthusiastic days. She, and a couple of other equally intense players, earned a title which is revered still in WoW circles.
This achievement brought an incredible level of respect then, and continues to do so even now, as far as I can tell (I don't play so much any more!). The number of hours involved varies depending on the character you use to pursue the goal, but most people will take months of regular play to achieve it.
I no longer play WoW except for the very occasional jaunt. But I've just embarked on what has the potential to be my very own Insane achievement.
Behold. My first five 2 inch squares. I have no clue why I'm doing this, nor what I'm going to do with them. But they are utterly gorgeous in their crazy minuscule cuteness.
