We thought the whole "level" thing was enough of an indicator of achievement in World of Warcraft, but apparently not. Word on the internet is that the Lich King expansion may introduce an Achievement system to the game.
According to some screens posted on a site called deathknight.info, achievements spotted include leveling characters to 80 on both Alliance and Horde factions, and completing a daily quest each day for five days.
Blizzard aren't talking, saying only: "We haven't made any announcements regarding this type of system for the game, and we don't plan to comment on rumors." We think it seems possible, verging on probable.
