I think I went a bit off topic here in terms of your questions, sorry about that:
I'd love to meet someone named after a video game, but I don't think I ever have. I've met people named after other fictional characters (an Indi, an Ezri, a
Morgana, a
Sterling...). I did meet a
Gaia but I don't know if she was named after
Gaia from one of the games that feature that name. I do know that her mother's engagement ring was three diamonds in that "Triforce" symbol from
Zelda so I suspect that
Gaia may have nerdy rather than mythological reasons behind her name.
I'm a wannabe gamer, so I could see myself using a video game name. Unfortunately I don't actually play many games! I know that I really liked the name
Garnet for a long time because of the princess from Final Fantasy 9. In the game you're supposed to change her name so she can live undercover, and I remember I didn't change it because I liked
Garnet so much. Also
Vivi from that game made me like Viv-names.
Vivi was sooooo cute.
I love the idea of people being named after fictional characters, but the problem is that I've never really done a proper playthrough of a game, never really immersed myself enough to get attached to a character or liked one deeply enough that I'd name a kid or even a pet after them. It takes me YEARS to get through a game, if I finish at all, because I don't dedicate hours and hours to it. I'm super casual.
Kirby is a name that I might like more if it wasn't heavily associated with a game. I love the little
Kirby character but it's so tied to that round pink thing that it's hard to see it as anything else now. I'd maybe name a roomba
Kirby.
