(Suggestion) FFXI Achievments
I think it would be a nice feature to add to the game that a few other mmo's have. Maybe a in-game feature to compare your acomplishments to others in the game across servers.
Relics, jobs, crafts among other things.
I know of some in other games that play specifically working towards those goals set by the achievment systems implimented in those games.
Maybe even give in game rewards based on meeting specific goals. Just the same as maat's cap is a reward for beating maat on all the jobs. But mostly I would like to be able to look at friends achievments just to compare.
