Harem : Yep, basically, most of characters will have the same concept/gameplay as MC's girlfriend, with specific interaction/feature and/or variations on paths
NTR : What I have currently in mind is to make paths somewhat relate to one or several related "genre", NTR being one of them
Femdom/Lesbian/Futa : It's kind of a tricky question as I'm aiming to do a sandbox game ;
Currently those 3 are "avoidable" as it's not gatekeeping other content, but if there is still a possibility of happening ;
Also I don't want to announce a disclaimer before each "event"...
So, the most feasible solution that I think of is implementing "tags visibility settings" to totally make some unwanted content disabled ; I'll see what I can do but besides the UI part, it shouldn't be too complicated !
