If you at least know how to play videogames and don't act annoying, then it won't be bad. I mean, you're not going to talk much, but that's about it. A grown up Gaz would be just...a silent type. Chances are, she'd probably just live off neetbucks from her father or get money from gaming or something, but other than that it'd be pretty normal, at least if she's actually into you.
Mandy's just straight up evil.
