While most companies were driving themselves crazy at E3 this week, Blizzard quietly confirmed rumors from early last month, officially announcing achievements for World of Warcraft, coming with the next expansion, Wrath of the Lich King. Achievements are broken up into several categories - PVP, Dungeon and Raid, Quests, Professions, Events, World Exploration, Reputations, and the more whimsical General category, which includes an achievement for getting a shave and a haircut using WotLK's new barbershop feature.
Some achievements will carry rewards such as tabards, pets, and other prizes, and Blizzard promises more with each new content update. Players will be able to compare their achievements with others both in-game and via the Armory.
My girlfriend just got her first character to 70 this week, and asked me what she could do now. If she can be patient it looks like Blizzard has an answer forthcoming.
