I have played too many games like this the last few month because I'm a lot more at home and still most of the time alone.
Because of that a lot of characters get mixed together in my head. And if I pick up the newest version of a game which I havent played for a few month, it even hard for me to remember the girls names. And I'm usually too lazy to start over again from the beginning unless I don't have to.
Therefore I cant be sure if I remember correctly about Coral (the youngest/gamer chick).
When I played the game a while ago I thought she was written a bit too steriotypical. Like what you would expect from a gamer chick if you didn't know one.
I have watched over the years a lot of different gamer chicks, reactors or just basic nerd girls on youtube/twitch and other sites.
They usually have something what its hard to explain... I wouldn't call it a quirk, a tick or something similar....hard to explain.
Coral didn't feel genuine or "real" for me.
But I think a similar problem might apply to other people who are familiar with an area of work which is in the game...for example a lawyer might say that Zoe act like a lawyer.... or something else.
just my two cents
But you could maybe some "research" if you find the time and watch some nerd/gamer chicks on youtube or twitch
