World of Warcraft's Armory (Blizzard's spelling, not ours) has been updated to include the Achievements and statistics added to the game in last month's Echoes of Doom patch.
The Armory is an online database of characters, equipment and other WOW info that's linked to the live game.
You can now track your own Achievements, look at other players', and run comparisons between up to four characters simultaneously as well as browse the full Achievement lists. You can also do all the same things with lifetime character statistics - total damage received, number of quests completed, and so on.
You can also view statistics on the demographic make-up of guilds in terms of character race, gender, class and level (24 per cent Death Knights, surprise surprise). This is in addition to the online Guild calendar that was added last month.
It's a haven of delicious time-wasting detail, all wrapped up in a very slick, pretty and intuitive interface. It's still painfully slow though.
