Currently when someone kins a character they immediately know the characters "true name" which is an immutable and unique name for each character and seems to be one of the oldest sacred cows of RPG's. But names are in fact entirely SOCIAL constructs and are not immutable, false identities and alias have been part of history for ages and add an element of intrigue to social interactions.
I propose that instead players not actually have these kinds of True Names, a player instead has a mutable "Giving Name" box on their Kin list. A person kinning the player by Hearth Secret or who accepts a kin request from the player will receive this name at the time of kinning. Later changes to the Giving name will not update what the other player has received. When accepting a kin request the player will have a text Box in the pop-up with their current Giving name already entered, they can enter a different name though before accepting and that will be what the kin requesting player receives. As with the current system all players can re-name people in their Kin lists and see those names for themselves without effecting other players.
Some of the effects
* Annoyance and frustration from not being able to create characters with a desired name, particularly of dead characters
* Allows players to simply rename themselves at any time, a freedom denied in nearly all other online games
* Allows disgraced or infamous players to 'start a new life' under a new identity (for good or ill)
* Rewards the clever juggling of alias by any criminal element or spies, as opposed to the more 'gamey' use of alts for the same purpose
* Increases the importance of description system to foil the above
It may be possible to implement this by simply converting every players true name to their giving name while leaving kin lists unchanged, but its possible that the codez do not support it. Also the removal of True names would tip the scales in favor of the criminal elements so some compensatory change in the justice system would likely be needed to maintain present balance (assuming you believe it to be in the proper place, which is a whole other topic).
