and it seemed that around 50% of the H-scenes contained gay content.
Yeah there's plenty of it, but it's not compulsory... So hypothetically if someone came to this game determined to view only straight, vanilla content (i.e. no gay, futa or NTR stuff) they could actually do that... They'd be cutting themselves off from maybe 2/3rds of the total content in the game, but it
is an option.
Whether that's worthwhile or not is a calculation they'd have to make for themselves.
But IMO this game is at its best when you play it like Corruption of Champions, and allow yourself to be a little challenged. You know that squeamish feeling when something is erotic but you're still just a little uncomfortable with it? That's when the game really shines.
And while the NTR content basically has a single gate that will either enable or disable it, the gay and futa stuff is almost all handled on a character-by-character basis, and it regularly gives you the option to back out of individual relationships.
(Personally I wish the NTR haters were challenged on a case-by-case basis too, but they're so goddamn whiny about it.)
