My nickname came about when I was joining Xbox live back when the original had released it. I wanted a better name than what I used to have, so I attempted to use different names. Each one failed, obviously, because there was a large userbase by the time I joined(Six months in, I believe). So I tried Unreal, which was taken. Interesting thing is, Xbox suggested several other names as alternatives and I picked this one. It's stuck with me for the last 5+ years, and it's still a very cool name.
