Continuing on with my "thinking about wow too much" line of thought...
One thing that is missing from World of Warcraft's armory and achievements and I believe Warhammer's tome of knowledge or Lord of the Rings Online's deed log are dates. Dates when you accomplished something. WoW's armory has your date of last logon. And Everquest's character sheet goes as far to show how much you've played.
But as far as I know there is nothing that shows a history of your character. And what I mean by this is, there is no easy way to tell a 4-year old WoW character from a 30-day old WoW character. There is no stardate for when you first looted a green upgrade, or when you killed the Baron within the time limit. Yes achievements are covering some of the bases here. But what about doing something pre-nerf or level appropriate, dates would take care of that.
Warcraft realms is the closest you'll come to having a time line.
There would be costs for maintaining that data I'm sure. And the risk of being able to stand apart due to time played is bad for overall business when it comes to recruiting players (Sure *you* have 150 AAs, but that looks like Mt. Everest to a new player). And...it's not something players have been clamoring for.
So maybe it's not such a great idea. I'm just an "old" player pining about the days when I first started playing. Ought Four 'twas.
