Is it okay that I name nearly all my WoW characters after characters in your books?
Nah, I find it flattering. Usually. Whenever a new game or MMO comes out and someone's already sniped Haern or Harruq, I grumble a little bit, but that's when I break out the lesser known characters.
My brother, on the other hand, is less amused. He's been naming characters in MMOs 'Tarlak' for like, fifteen years at least since we first started playing Ultima Online in high school. Whenever he has to use 'TheTarlak' instead, trust me, I get to hear about it ;-)
