unveiled an achievement system -- much like Steam, Xbox Live, Trophies, etc. -- for World of Warcraft. The categories of achievements include PvP, PvE, world exploration, professions, and character development. Some are simple (give 10 hugs), some are very difficult (completing high-level raids). Additionally, there are "Feats of Strength," very difficult or now-impossible achievements that don't show up if unearned. The Feats are worth no points. No word on if the achievement points are worth anything.
