Here is my belief;
EVEonline is a game where trust is the most valuable commodity any player have to offer, whether they offer it or not doesn’t really matter, this also brings a common phrase to mind “Best ship is FriendShip”. A characters name is not only used to measure ones trust based on various actions performed by the character (player). With EVE being the (Sandbox) game it is; naturally all actions a player takes using an alternate identity (character with a specific name) will also have consequences.
We’ve all heard about one or more times where EVE have been brought up in various newspapers, even in TV-news reports?, telling tales of how one character planned and executed a malicious scheme, that’s has taken years in planning, and has even taken years to execute to perfection involving building trust and climbing the ranks within a Corporation/Alliance only to backstab and rob them blind when they least expect it! While it may not have been for this sole purpose but some have become legends in the EVE community.
In a story driven world, more so than any other MMO(RPG) game I’ve ever played, EVE stands out on top due to it’s “rename”-policy (as in it’s not possible to do).
A character’s name could be compared to a person’s social security number (the number that everyone is given at birth, may vary from country to country but it serves the same purpose) which is a unique identifier that can’t be changed no matte how much you may want to. You may chance the way you look, your name, where you live and so on, but your social security number will always remain the same.
I do firmly believe that CCP would not even think about making it an option to rename a character based all the things that are tied to a character’s name; Trust, Mistrust, Reputation (Player to Player), Actions and the consequences that follow. @CCP_Falcon is free to correct me if I’m off the mark here.
on a side note;
There have even been studies where scientific communities have used EVE as a way to examine human behavior in various situations.
