How did you pick your username? Character limits. I wanted to change my Xbox username (I used to go by something else) and it cost money to change it, so I had to think carefully. I was really into Halo and I wanted to be "[Blank]Spartan," and this was the only one that would fit and wasn't taken.

Shock of all shocks, "DarkSpartan" and "ShadowSpartan" were already taken (I almost settled for "ThePizzaSpartan"). "DarkWing" just popped into my head, sounded right, and it fit. It didn't even occur to me that it made me sound like Darkwing Duck until much later (that was a complete coincidence).
