My idea was a simple gender swap and nothing to do with the roles themselves so they wouldn't take away any screen time or development of the existing female characters. This is more because if there is a female plot-related character (let's say we replace Tony with Tonya), then at least we still get some eye candy during plot-focused part of the game.
It wouldn't make sense that almost every surfer were girls.
People forget that an AVN could tell a story too and that's why I disagree when people were crying about the sister being not fuckable in his last game. When you see their relationship, it couldn't be otherwise.
As for Domino Beach to make a credible group you need guys (irl I see more man than woman surfing), and the game want a "crew" with people being friend. You need girls and guys for that.
I think it's pretty normal + they were talking about relationship between members, you can't make them all lesbian.
As for the development if there was more girls, people would have want them fuckable, that means more options/time to make updates.
You need to think in another way : All the girls are already here, and if there weren't any guy there wouldn't be more girls. With that statut, boys are only bonus to put more emphasis on the mating/crew aspect and credibility of the game.
The rebels guys do seem fun, and the other ones are rivals so it's okay.
+ there is girl in every single group we've seen (Fiona for the bar, 2 girls in the rebels, 3 in the kings, already 2 in the lafeguard post and there is probably more, even 1 at his old job !
And there probably will be more of them in next chapters. I think it's already enough.
I would just have trade one brunette for an other hair color, because there was a lot of them (and some does look a little bit alike) when we've seen one redhair and two blond girl but it's not a big deal either.
Edit :
People are already talking about their favorites...
I would say the blonde girl that we didn't really see, she looks absolutely stunning.
As for girls we know my big 3 are Carla, Riley, Fiona atm.
I do like Zoe or Olivia but not as much.
