but in the absence of better criteria the success of a character can only be objectively measured based upon the opinions of those who interacted with it.

Of course, one could also draw hypotheses about the player's subjective opinion of his/her own character based upon the events in the characters life.

Griimbling was the leader of a cabal, had a special weapon, and got a lot of positive immteraction.

Corthy was removed from a cabal twice and was given a negative title.
