Hahaha, I'm not sure if it counts but Neopets was my first online gaming community when I was but a little girl... Couldn't have been older than 10, I think? I adopted an Acara but soon enough I became obsessed with getting a Cybunny and ended up spending its special day in April (forgot when it was) refreshing like it was my last day on Earth. They must be dead by starvation by now, the guilt.
Years after that I ventured onto MU Online for a while, but as everyone around me became obsessed I lost interest and slowly abandoned it altogether. Not sure if it has happened to you before, but with all my friends and acquaintances talking about it, I became over-saturated and got fed up.
