does anyone here name their character after a Greek Hero or Heroine?

Nope. Shasow is my name, as always. I discovered it a long time ago when I misspelled Shadow for when I was playing World of Warcraft a long time ago when I was younger.

If dirtbag is a greek hero... erm

Not yet, but I will get to it eventually. I get most of my character names from mythology and history. In Oblivion and Fallout 3 I have had Artemis, Artemisia, Hera, Nyx, Penthesilea, Medea, Kirke, etc...
