Yeah, I was a gamer for years, and I can tell you, when people use an alias, it becomes much more impersonal, and it allows your brain to shape whatever for to the name. If someone goes by "DarkSoldier" and is an idiot, your brain associates that name with an idiot, it matches an identity. However, if "Dark Soldier" is actually "Benjamin Rochester" all of a sudden it's an identity that holds it's own.
I've always believed this, so I have a nickname (Feng) so that people can remember something unique, but everyone calls me Adam, and I never use Feng. I use McC because nobody wants to spell, pronounce, or read "McClellan".
Very good idea.
