Even though it doesn't have NTR/NTS now, when they add it I wouldn't even consider playing, so it's better not to play at all. Why play it if characters I might like are going to be ruined by that crap content? Just because it's optional doesn't change the fact that the LI is going to do something questionable unless you avoid it, therefore ruining the character. It ruins your perspective on that character.Good luck with your game. I don't know what audience you're trying to attract since you haven't added NTR/NTS yet, but it's definitely not going to appeal to people looking for something more vanilla or harem, since they hate that kind of content in their game and just reading that it has NTR will make many avoid the game, even if optional.
