I used to play Atlantica online. I had a weird fascination with the crafting system and the market side of the game, very amusing. That's not the obsessive part. The obsessive part was a pair of stat boosting wings that were being offered as a prize for playing some minigame pirate thingy on a partner website. The high score was 400,000 when I began. It was 800,000 by the time I was finished.
I won the wings. ;D
