I thought everyone in my generation played Runescape during middle school and occasionally through high school.
I'm not much of a diehard gamer, but I spent a few years actively playing RuneScape (2003-2006, 2007, 2009) under the username Treck40 and, more prominently, Alexian Cale. Never managed to achieve a high level on either account, but I was involved for the sociopolitical and roleplaying aspects. Led a couple of successful clans/guilds, became heavily involved in the in-game politics, achieved considerable notoriety for my tactics and conduct.
Good times. Especially when you had dozens of people three times your level call you 'sir'.
Come to think of it, that probably explains everything about my behavior since then.... mmm
