I had read
1925 Things Mr. Welch is no Longer Allowed to do during an RPG, specifically "128. Polka Gnomes exist only in my mind." Gnomes were always my favorite race for playing on my favorite Battle of the Dragons server on Neverwinter Nights if I wasn't in the mood for trying to create a completely serious character, few things are more entertaining than a nude, bright pink barbarian/bard/red dragon disciple gnome wielding a dwarven war axe slaughtering everything in his path and taking down the enemies' dragon with little to no effort. Add to that my taste for random and silly names and there you go.
The last two names I used a lot were Xanthil, which was just a name I made up for an evil mage character that I ended up using elsewhere for a while, and back when I was playing Mechwarrior 3 and Mechwarrior 4: Mercenaries I was known by TW_Omega. Nowadays I always wonder why so many kids/teenagers use Omega as a screen name, I can't even remember why I chose it myself.
Other names I frequently use for online games are, in order of most common usage: Pariah, Raging Bob, Hunter Harold, Takari (female MMO characters), Mikari (female MMO characters) and a few others that I can't remember at the moment. I think my favorite is Pariah, because I got tired of always being called a hacker/glitcher/cheater/etc. in FPS games so I decided to go ahead and give myself an appropriate name, that and I was thinking about the Pariah Dog random encounter in Fallout 2 the first time I used it.
