You don't have much to fear actually. Your statement "Obviously those who like futa are going to get way more content than those who don't" couldn't be more incorrect lol.I want to know how much of the story if I avoid futa...I hate it? Obviously those who like futa are going to get way more content than those who don't..so is it possible to give more content to those that don't want futa to at least equal out those that do? I like the characters *i haven't played this latest update yet, so that could change lol*
Normal characters and futa/trans characters will have plenty of content. The only that'll be optional will be the nsfw scenes for the futa/trans characters. All optional content will be clearly labeled too.
So long as you turn down their advances, then you'll just have a good friend with a pretty face, so to speak.
All that being said, the game will most heavily feature females over futas/trans.
