This reminds me of the episode of Red Dwarf where the crew die and find themselves back on Earth, having been playing a video game for four years. Kryten is delighted to discover that he is really a police officer called "Jake Bullet, Cybernautics Division". Of course Rimmer points out that the Cybernautics Division might be traffic police and perhaps he just happens to have a hopelessly macho name.
I find that on the whole fantasy names tend to have lots of "a", "e", "y", "z", "s" and "th" sounds. And apostrophes. In fact, names like that can put me completely off a book. I remember a book I once read in which the main character was a farm boy called Farnor Yarrance. Right. In just about any rural community that would be shortened to "our Farrie" or something pretty quickly.
(My group mostly plays games set in particular periods of Earth history, so for most of my characters and NPCs I look up appropriate names -- mostly to avoid falling into the trap of thinking up an overly fancy name.)
