Nothing wrong with gamertags/handles, so long as they aren't used for subterfuge. I've had plenty of handles on forums and in games over the years, but I have never used them as aliases -- that is, in the sense of concealing my actual identity.

Well, it probably helps that I can never think of any good video game aliases... :)

I agree, real men game under their real name.

This is the MOST impressive alias.

How do you not have a more impressive alias?
