In '92 I started by using "Slick" for racing and flight sims. After a while there were too many Slick's running around so I became slick203 and for the last 10 years I've been "SlickDevel" in all my other sims so I'd probably go back to that.
My nickname was "sad555" before getting licensed. But i stopped using that stupid nickname and turned to "WereSloth", so that would be my username as an unlicensed.
I think "Painkiller"
Something a few friends started to call me, since I played that game alot a few years back.
It's actually one of my top favorite fps of all time.
I was 13 and started playing some online shooter of which I can't remember the name. I took DYRWK as a joke, for when people asked what it meant. 'Do you really wanna know'?
