Never heard of the video games mentioned below. Most people probably haven't, as most people don't play video games. Also, I think that kind of popular usage unreasonably scares people away from using names, as even at the worst, the names will be popular for only about ten years before the popularity and association dies away. People are already naming their daughters Hermione again without concern about the Harry Potter link. Anyway, I think of only Zelda Fitzgerald when I hear the name. Sophisticated, literary, and everything that was good about the 1920s. Very nice. A cool nickname could just be the initial "Z."
