Oh it happens. I tend to think a lot about my hobbies... especially if I'm super into them. I haven't been part of a group rp in yeeeaars. And I love it!
My oldest is named after a character I played for a handful of years.
We, my RpN name was my first MMORPG character's name (from Everquest I, not II). I had a 6 year old brother in law start playing who named his character after me.
