My girlfriend and I have discussed using the name Jullinar (not videogame, but it's the main character of my book... Jullinar is an angel)... And as far as videogame names, I think I could pull off Lucca. It's just an alternate form of Luka, which I believe is a fairly normal name anyway.
I should get my friend Kether in on this... She has 5 kids, 2 of which are named Sairi (Kairi?) and Aidan (suspiciously similar to Aden, the main continent in Lineage 2)... And her whole family has weird names. Course, she doesn't know JACK about videogames, LOL! She just happened to pick those names. She'd probably take a lot of inspiration from the Final Fantasy names though!
I can see naming a daughter Celes... Hmm... And yeah, it WOULD be cool to know someone named Samus.
I canNOT see naming a girl Tifa though... #1, it's just a little too far. #2, what if there are still FF7 fanboys when my daughter gets older? (Sounds crazy, but look how old CT is and here we are!) Because of the name Tifa, she'd get made fun of by boys in school if her breasts don't turn out humongous...
