For me it's a GP for a boy. The city is nowhere near my first thought.
First thought:
Vega is a (male) character from Street Fighter and I used to play that a lot when I was younger.
Second thought:
Astrological associations. I kinda think the meaning is more fitting for a boy as well.
Vega for a girl would be nice. It feels like the same category as
Nova, which I like a lot.
