My name came to me because its my name. I wanna change my real name. And also on Devbest but in order I need to subscribe but no thank you waste of money.
Long story short, my school used to have a Game Centre where all the gamers would go during our lunch breaks. During a game one of my mates said "you're as fast as a mirage Andy" and then I took it, compliment or not, and made my gaming name mirageboss.
From 2008 to 2010 I was known as veelox, this name came from a private game server i played that was called veelox - and I just liked the name.
From 2010 to now, the username Roper was actually inspired by my friend's surname (Roper) - I guess It just sounded cool at the time so I've stuck with it.
