I remember reading an article about perfection, which I agree, but I can't find it, so I'll summarize what I can.
In many MUDs, people want to roleplay, and therefore, they want to create so-called "special" characters. They usually resort to hackneyed sterotypes, such as Mary Suedom. The question the article raises is this: If there is an incentive to create Mary Sues, would being Mary Sue actually be special?
Say, everyone creates a character who makes one million dollars per year. That's great. But since everyone in the game has a million dollars, relatively, everyone is equal. If somebody creates a character who has a billion dollars instead of a million dollars, only that character becomes "special" while everyone else wallows in poverty. And if somebody creates a character that "only" makes $60,000 a year, I become "special" too, but more in inspiring pity rather than actually inspiring awe.
Same thing if everyone is pretty. If everyone is pretty, then it's just average, you are expected to be pretty, there's nothing really "special" or notable about it. If someone creates a character that is UGLY, that gets you some notice and attention, making you more "special" than other people, altough it will cause people to dislike you.
The article was mentioning this as an argument against perfection, but I actually wonder more and more how would a game work if everyone plays as perfect beings...
