Blizzard has prepared a preview of the Player Achievement System, which will be introduced to World of Warcraft with the Wrath of the Lich King Expansion.
While Wrath of the Lich King will improve many of World of Warcraft's existing features, it will also introduce plenty of brand-new ones to keep the game fresh and interesting. One of these new features is sure to suit a wide range of play styles: achievements. These self-contained goals will offer new challenges, satisfy goal-oriented players, allow others to see your accomplishments in World of Warcraft -- and are just plain fun.
World of Warcraft's achievements system will launch with more than 500 individual achievements covering every aspect of gameplay, including world exploration, PvE, PvP, professions, and character development; from the purely whimsical to the truly epic, there will be something for everyone. Some achievements come with in-game rewards such as tabards, vanity pets, and titles. All of these rewards are purely cosmetic and just for fun, but you'll certainly stand out when you proudly display them.
And don't fret about running out of achievements anytime soon. The list is easily expandable, so you can expect additional achievements with each new World of Warcraft content update.
